Yes it does. The texture files are the same.

Don't know if this is the right place to ask,but any thoughts on making something similar for Tokyo Xanadu Ex ? It seems to be using the same engine as the Trails games,also features the obligatory japanese bathhouse scene.

 

Ok, I bit.  I was withdrawing from CS4, and started reading reviews, and then I saw that it's 80% off at GOG, and so I couldn't help myself. I deleted all the skirts.

Well, let me explain why I want to unpack and pack the phrye files.
Not for NS, of course, I'm only interested in PC game mods.
My purpose is mainly to get the skeleton.
Because using 3dmigoto I can only get the meshs and textures, not other things, especially the skeleton (maybe there is a way to get it, I don't know). 
With the skeleton I can adjust the weights，so that the model does not deform when doing various actions.
But so far it looks fine, even without adjusting the weights there is no big deformation.

 

I'm just interested in trying to see if I can get it.
I tried the links you provided and those tools can't get the skeleton. 
It seems like you said, I have to research phrye engine. 
So I've decided to give up and thanks for the help you provided. ?

 

Hey, I found a tool to convert the pkg file to gITF format (.glb), directly importable into blender.

I honestly have no idea what I'm looking at, there's so much going on here.  But I see that there are 133 bones!  Is that the skeleton you were looking for?

Yes, this is the skeleton I was looking for. Thanks.

 

I haven't figured out what to do with it yet though.and I don't have any mods I want to make right now. hahaha.......

Still, thank you!

You’re welcome!

[amorrow28]

YASSSSSSSSSSSSSSSSSSSSSS!!!!!!!!!!!!!!!

 

So worth the wait!  Thank you for not giving up, @Whayameen.  ?

 

First, I was like, wait, when did this happen?!  Then I realized what you did, and I realized all the work that went into asset injection has paid off.  ?

Tutorial time!  (I'm bored)  Let's make Juna's breasts bigger in @Switch608's mod.

 

 

For reference, making this mod this took me about 5-10 minutes.  It took me WAY longer to write the damn tutorial.  Also, I know it doesn't look very good - I just did it to prove to myself that I could.  I know you can do better.  ?

 

 

 

Ok!

1. Open Blender.
2. Import Juna.ib/Juna.vb (File -> Import -> 3Dmigoto Raw Buffers)

  Reveal hidden contents

3. Click on the mesh, and go to edit mode. Change to Face Select.  Zoom in (mouse scroll wheel).

  Reveal hidden contents

 

4. Select breasts (easiest way is to use the circle select tool, then you can paint over the triangles you intend to modify).  Left click (hold+drag) to select, middle click to deselect.  Be sure to look at your selection from multiple angles before moving on to the next step, it's easy to miss random triangles as you paint!

  Reveal hidden contents

 

  Reveal hidden contents

5a. In Juna's model, not all the edges are joined, we will need to fix that first.  Select one layer further out than you need (basically paint more of the breast than you need).

  Reveal hidden contents

5b. Merge by distance (this removes any hidden edges where two triangles are touching but not joined together).

  Reveal hidden contents

5c. Now use the "select less" function to shrink your selection (see why we selected more than we needed in 5a?).

  Reveal hidden contents

6. Now you can make things bigger.  Use the shrink/fatten transform (Alt-S).  Move the mouse up and down, and your model will get bigger or smaller.

  Reveal hidden contents

7a. Now we need to move the bigger boobs into place!  Use the transform tool.

  Reveal hidden contents

7b. Grab the inner white circle and tug downward and outward.

  Reveal hidden contents

7c. Be sure to examine from all angles, if you were tugging while at a funny angle, you might have pulled to the left, or the right...

  Reveal hidden contents

8. Time to export your work!  Save as "Juna" (to make your life easier, keep the same name as Switch608 used).

  Reveal hidden contents

9. Go to the folder where you saved your file, and copy the .ini file from Switch608.  Do this FIRST!  Then copy in my vb_split.py script, and run it.  If it finds a matching .ini file, it will NOT auto-generate one.  (We don't want to write our own, we want to re-use the existing one.)

  Reveal hidden contents

10. Switch608's mods use a different filename convention from my scripts.  Edit the .ini file and change the filenames inside the .ini file.  (Yes, you could just rename the files themselves, but then you'd have to rename them every time you run the splitter.  And you'll probably run it quite a few times as you make small changes in Blender!)

  Reveal hidden contents

11. Copy the file into your Mods folder, and load up the game!
12. Admire your work, and then go back into Blender to adjust as needed.  (You might want to shrink the nipples back down, for example.)  Don't forget to run "vb_split.py" every time you export from Blender.

 

Hopefully this inspires someone to do some modding!  Don't ask me to do it for you, I won't.  The whole point is to teach you to fish!  I hope you try it, and if you like the results, I hope you share your work with all of us.

 

Thanks to @amorrow28, @Switch608, @coomi for great work and tutorials

I love CS4 so much that after seeing so many girls in short skirts, I decided to play the game again to experience every great shot.

I read the tutorial brought by amorrow28 seriously 3 times. I thought there were already a lot of skirts that could be removed. Once I had a chance, I thought that since the skirts could not be removed, is it feasible to remove the clothes, so I started various attempts.

Girls who made improvements in my first batch included Juna, Larua, Aurelia, Musse, Sara, Alisa, Emma.

 

Improvements include less fabric, bigger butt, and more thongs, I love thongs so much

 

One of my favorites was Emma's magical look, I tried a number of options and finally settled on having her with the least amount of fabric, while also modifying her braids to be less long and not obstructing my view.

 

Finally, thanks again for the modification tutorial brought by @amorrow28, I wish every enjoy game.

This is the attachment, I don't know why it dropped

 

If you are using @amorrow28's CS4_UnSkirtMod_v1.3a file, you can replace my file with one click. CS3 and Hajimari should modify the corresponding hash value, but you can try it out, remember to back it up?

Great contribution, thank you!  I love it when people use my instructions and tools to make something that makes me wonder - how did they do it?  (similar shoutout to @coomi - clearly you knew more than what I described in my tutorial!)

[lakovic]

I learned from your @amorrow28 tutorial to delete objects through meshes, zoom in and out, and I tried to see if these meshes could be deformed, and the result was feasible!

 

Import the mesh, select the object, and import it in blender. About how to import, @amorrow28's tutorial is very clear

 

 

1. Select the Object Mode you want to modify through the object mode, here is the clothes as an example

2. Switch to Sculpt mode

 

 

3. Tick Wireframe
a, while ensuring that the X-axis symmetry is selected

4. Click this button, it can deform the mesh, and at the same time there are several deformation tools similar to the upper and lower icons on it, you can try them all

 

Look at the picture, there is a circle outside the yellow point is my mouse position, this circle can be adjusted in size, when the X-axis symmetry is checked, another small yellow point will appear. At this time, I drag it to both sides, operating like an arrow

 

You can see that the clothes have been deformed

 

At this time, you can export the mesh to see the actual effect, but the export in the sculpt mode is invalid. You have to switch to the object mode to export. I don't know if it is a bug in blender 2.83.

 

 

In the game, you can see that the clothes are already long.

 

 

 

So all the characters I modified, their bodies, and clothes, I slowly made them through the sculpting mode, and I had to switch various angles in the process to ensure that they would not be deformed. I believe there is a better way to operate, but I really don't know how to operate blender, so I can only use stupid methods?

[coomi]

@amorrow28 It was enough for me to get a few pointers on where to start. Blender's UI is a nightmare to navigate and knowing where the basic functions are was very helpful. 

 

I'll show off my general workflow for smaller breasts. Consider this an extension to the Juna breast enlargement tutorial. 

 

Spoiler

I like to start by making three vertex groups for the breasts; one that has both, one that has the left breast and one that has the right breast. This is helpful when you want to move the breasts around. Just remember to delete these when you export the model or you will have nightmares.

I usually start by flattening both breasts using the green axis on the scaling tool.

I then move them into place with the transform tool.

I also like to move the breasts closer together or rotate them around. 

Alright, now we have this mess. Enter sculpt mode from the top left. There are a lot of interesting tools here, but for me the most useful one was always the clay tool.

You can modify the settings of the current brush from the panel on the right. The most important settings are brush radius, strength, direction and autosmooth. Play around with them for a while and figure out how they work.

The symmetry option at the bottom is also useful to remember. It is enabled by default, but there will be times when you want to disable it.

 

After some smoothing I ended up with this.

I wanted to bring out the nipples a bit, so I went back into edit mode and used the scale and transform tools.

You could also experiment with the flatten tool in sculpt mode for this; it has a secondary mode that increases contrast.

 

Next I used the grab tool to pull everything closer together.

 

I smoothed everything a bit with the clay tool and then used the crease tool to add a hint of depth. 

 

Then as I swap to object mode, the model looks like this. 

We can fix this. Enter edit mode, select all the vertices that look weird and recalculate normals. You can pretty safely do this for the whole body if you don't feel like painting. You may want to avoid the neck and hands as weird seams can appear there.

Finished product.

Remember to delete any extra vertex groups you made at the start before exporting.

 

From my experience, small chests are much easier to make than big ones. You can make vague mounds and they will look fine in game. With big breasts you need to be able to sculpt a shape that's actually recognizable as a breast, and that's not easy. I probably spent more time smoothing out weird lumps on on Elie, Emma and Sara than I spent on all the smaller girls combined.

[amorrow28]

@lakovic and @coomi, no joke, I have never clicked on the sculpt tab, thank you.  I don't care if our mods don't get 100,000 downloads like the skyrim ones, we have the best thread on the forum!  ?

Ladies (?) and gentlemen, after a bit of trouble I present to you: Trails of Cold Screens IV -THE END OF SAGA-. A 300+ image long action-PACKED, degeneracy-FILLED, ASS&TIDDIES EXTRAVAGANZA featuring your favorite Kiseki waifus in crispy 720p. This album contains spoilers for both Act 2 and Endgame BUT they are hidden away behind multiple folders, so if you haven't beaten the game just don't open them and you'll be fine, otherwise feel free to put everything into the same folder.
 

Enjoy, and comment your favorite screenshot if you feel like it!

(this fucking box keeps turning small no matter what I do, I'm so sick of it )

Additional fluff:

  Hide contents

This took a while to get done because last week my notebook decided to eat shit and wouldn't stop blue screening. The only solution available at the time was to restore to a point far earlier than the day I started taking the screenshots, meaning I had to sacrifice 70+ images, among other things. That was very... frustrating to say the least. Taking screens isn't hard, but it is time consuming, and this made my motivation go way down. Still, I really wanted to have a definitive show of appreciation to the community so I just said fuck it, re-took the screens and added a couple hundred more on top of them. In my darkest hour I rose up to face the light once more, just like Rean... The Mean Bean Cold Steel Machine... 
 

A few more things: I wanted to showcase the Fairy Springs more, but sadly Rose has the only character model capable of grabbing huge badonkodonkas. I could've just replaced Juna with other well-endowed characters, but I prefer to have fitting combinations for this type of scene like Shirley+Elie/Duvie or Angelica+Alisa. The other thing is the concert; replacing Sully with certain characters/outfits makes the game crash (this doesn't happen with Schera for some reason), so I ended up showcasing only two characters. It's a bit of shame considering that scene is perfect to display some nice buttocks, but if the game didn't limit me I would just get stuck working on this forever because of how long that scene is, so maybe it's for the best that it didn't work out lmao.

 

And that will be it for Cold Steel screenshots, unless someone releases a butt implant mod for Duvalie and Tio or something. Kuro is releasing on PC next month, so if my notebook is able to run it (and someone releases a Free Camera script for it) I'll take some quick screens of that, if not then my next target is Reverie. That won't be for a while though because I'm a bit Kiseki'd out after working on this for so long 
Anyway, with all that being said I want to once again express my gratitude to everyone who contributed to make these already awesome games even greater.
@S_S_Majin @Switch608 @coomi @Zero_Fucks_Given @amorrow28 and lots more, thank you! You guys rock!

Amazing job! You deserve a break. It be great if Kuro is possible when it releases on PC next month.There's amazing girls Shizuna,Elaine and Rixia.

Iif not would love to see Hajimari characters with more Elie, Hopefully a full nude Rixia and Vita. That's just the back of my head.

[untestedpower]

Just gonna repost that I'm pretty sure these are all that's missing to give each character with bathing clothes a nude mod:

 

Spoiler

Millium

Aurelia

KeA

Roselia

Celine

Angelica

Nadia

Lapis

Vita

 

If they all get one then every bathing scene in the games could be a nude scene.

Info on how to use the nude mods with my mod here:
https://www.loverslab.com/topic/166239-trails-of-cold-steel-4-mod-request/?do=findComment&comment=3832221

 

 

Tutorial time!  Today let's port @Switch608's incredible nude mod from one character to another.  I'm going to use Hajimari assets this time btw (I chose Vita).  I'm posting this in the CS4 thread because all my other tutorials are here, and the exact same steps would be used for, say Aurelia.

 

Before we start, a shameless plug for my Tokyo Xanadu eX+ mod, where I learned to do this:

Spoiler

 

https://www.loverslab.com/topic/191860-tokyo-xanadu-ex-mods/?do=findComment&comment=3786184

 

Same as my other tutorial, you need to first set Blender (I'm using 2.93 LTS), plugins and python scripts up.  Basic instructions on setup at the top of this tutorial:  https://www.loverslab.com/topic/166239-trails-of-cold-steel-4-mod-request/page/13/#comment-3757792

 

Second, you want to know how to get a model into Blender in the first place.  Please try this tutorial here at least once, then come back:  https://www.loverslab.com/topic/166239-trails-of-cold-steel-4-mod-request/page/14/#comment-3767886 (minimum first 4 steps)

 

 

Step 1: Grabbing and loading models
 

Quote

 

Ok let's go!  Import the towel body mesh you want to replace (I identified ff7d439e as the hash of interest, and in my frame dump of Vita, it was index 000069 so you'll see it as 69 in all my screenshots).  If you don't know how to import by hash, see steps 1 and 2 of this tutorial: https://www.loverslab.com/topic/166239-trails-of-cold-steel-4-mod-request/?do=findComment&comment=3779614

 

Next decide your donor nude mod.  I'm going to use Switch608's Juna mod.  File -> Import -> 3DMigoto raw buffers, and import Juna.vb / Juna.ib.  I will need to see the weights as they correspond to the towels, so I went ahead and also dumped Juna's unmodded towel body mesh (hash c5a771b5, was 000004 in my frame dump).
 

Spoiler

 

 

 

 

Here you can see all three mods are loaded and overlapping each other.  Let's move them side by side so we can see all three.  Open the sidebar by pressing "N".  Choose Juna's original towel (#4 in my screen), and go to Item -> Transform -> Location -> X on the sidebar, and change it from 0 to -1 (negative 1).  That will move the mesh to the left.  Choose Vita's towel and change to 1 (positive 1), moving it to the right.  Now all three will be side by side.
 

Spoiler

 

 

 

 

 

 

 

Step 2: Weight Transfer
 

Quote

 

This is critical, the rendering engine uses weights to know where the bones in the body are (as far as we can tell) so mesh injection only works when the weights are correctly mapped back to the original model.  If not, some crazy stuff will happen.  We are going to use the manual method because 1. we are staying within the same game so all the weight groups already match and 2. the towel body mesh is missing too much weight paint to make this work with automatic mode anyway.  I advise you use the manual method whenever you can; I used automatic to make the TX+ mod because the groups didn't line up, but auto made for all sorts of problems.

 

You'll want to be able to compare weights, so 1. turn off "Lock Object Modes" (in Edit menu), 2. turn on X-ray view (Alt-Z), and 3. one at a time, click on each mesh and change to "Weight Paint" mode in the upper left corner dropdown so that all three are in weight paint mode.
 

Spoiler

 

 

 

In the window on the right, below the list of models, click on the triangle icon on the left to go to object data properties.  You'll see all the vertex groups.  Click on Juna.vb.  Rename all the groups, one at a time, by adding an "a" in front (e.g. "0" becomes "a0", "1" becomes "a1", etc).  You are doing this so that you can rename them again into numbers without going crazy (once 16 becomes 52, and 43 becomes 16, etc etc, it'll get confusing real quick).  The 'a' prefix lets you know if you've already changed it or not.
 

Spoiler

 

 

From top to bottom, look at the weight on the donor (left wrist in the picture below, group 0), and find the corresponding one on the recipient (group 16).  Go to the nude model in the middle, and change the name to the new correct number (a0 becomes 16).
 

Spoiler

 

 

 

Do it again, for every group.  Here, a1 becomes 3.
 

Spoiler

 

 

Notice that some of these are really difficult to see.  Xray helps a lot, but feel free to change the angle and look around.  You really really don't want to get any of these wrong.
 

Spoiler

 

 

Here we come to 8.  Look at number 8 on the nude mod, and you can see why it could be difficult to find on the recipient!  This is where having the corresponding unmodded mesh really helps.  I can see what 8 looks like on the unmodded mesh, and find its corresponding group (group 24) on the recipient.  a8 becomes 24.
 

Spoiler

 

 

 

Ok, after carefully going through every weight group, of course there was a group on the donor that isn't on the recipient.  I labeled "xx" at the time since it has nowhere to go.  I've tried just deleting such groups before and the game engine didn't like that at all.  (I zoomed in, you can see xx faintly on the left breast.  Yeah, that tiny thing can completely screw up the transfer.)

 

Spoiler

 

We will need to put xx somewhere.  I'm going to merge it into the left breast group (group 23).  Go to the wrench icon (modifiers), then "Add Modifier" from the menu, then "Vertex Weight Mix."  This tool merges two vertex groups together, combining their weight.
 

Spoiler

 

 

Fill it out like this.  This will copy all the weights from group B into group A (which will be the new A+B).  Set the groups A and B.  Set Mix Mode to "Add" and Mix Set to "VGroup A _or_ B" (not "and").  Press "Apply" and presto!  The easiest way is to set 23 as A and xx as B, then xx will be copied into 23 and you can just delete xx.   As you can see from my screenshot, I put xx as group A and 23 as group B instead.  Because 23 is so big and xx is so small, I couldn't tell if I was doing it correctly (esp since I'm taking so many screenshots as I go, I'm not always sure I actually did the action I was screenshooting haha.  In fact I went all the way to the end of this tutorial, the mod was broken and unuseable, and I had to revert to this step!).  In my case, since xx was the merged group, I deleted 23 and renamed xx to 23.

 

Spoiler

 

Go ahead and delete your group B.  (Don't be confused by my screenshot showing how to delete a group!  It's from my first attempt where I used xx as group B.  I had to go back and redo it, and my above screenshot is from where I used group 23 as group B, so I deleted 23 and renamed xx to 23 instead.)

 

Spoiler

 

Once you've renamed all your groups and merged the ones that didn't have new names, you're done with weight transfer!  You can delete the donor unmodded mesh (#4 in my screenshots) and move the recipient mesh back to center (set location X to 0 in the transform sidebar).

Step 3: Replacing the recipient model with the donor model
 

Quote

 

We're going to replace the recipient model with the donor model, but let's get the model to roughly fit first, because it's easier when you have the recipient model still there..  Notice that Juna is ever so slightly shorter than Vita.  We need to stretch out the model just a bit.  Zoom in on the neck so you can see how off you are.  Hold your mouse cursor roughly midline, and press "S" for stretch.  Move the mouse up until they line up.

We will need to be much more precise than this, and it's actually easier to just deform the final model one vertex at a time.  Before we do that, let's merge our models.  This needs to be done because all the weight numbers we changed above are actually meaningless - Blender will use them to reassign the real weights during the joining process.

 

The basic process is this - go into edit mode on the donor model, and select none.  Then go back into object mode, and then into edit mode on the recipient model, and select all.  Go back into object mode, and fuse the donor to the recipient.  Then go into edit mode - you'll see that all the recipient faces are still selected.  Delete the selected faces, leaving only the donor model!

 

We can't quite do that, because our donor has no hands and our recipient does have hands.  So instead of "Select All", we're going to select everything but the hands.  First, before we forget, select the donor model, go into Edit Mode, and select None.  Turn off Xray mode, it's no longer useful here.
 

Spoiler

 

 

Now go into object mode, select the recipient, and go into edit mode.  Make sure you're on Face Select mode.  Select the entire hand on both sides.  (This is easier if you hide the donor model, but I have it showing here so you can see exactly which panels should stay and which should go!)
 

Spoiler

 

 

Be sure not to miss even a single triangle!! I usually will delete the hands to see if I missed any triangles, then hit undo.  Ok, once you have both hands selected, Invert your select (Ctrl-I).  Now everything you want to delete is selected.
 

Spoiler

 

 

Go ahead and go back into object mode.  To merge, select the donor first (click on donor), then recipient second (SHIFT-click on recipient).  You should see the donor in red and the recipient in orange.  Don't do this backwards, or the wrong weights will transfer!

 

Spoiler

 

Press Ctrl-J to join the models.

 

Spoiler

 

You'll see your two meshes are fused into one.  Go into edit mode, and you'll see that all the faces you don't want are still selected.  Hit delete faces.
 

Spoiler

 

 

We still need to do all the precision joining before we're done, BUT I actually advise when you're doing this for real to stop here and export, and see what it looks like (even though the size will be wrong, head and hands will be detached, etc etc).  Why?  Because if you screwed up weight transfer, everything you do after will be pointless since you'd have to restart.  And I started with weight transfer because if you can't get that to work, the rest of this tutorial is pointless.  So skip step 4 for now and go on to step 5.  If your model shows up, great!  Come back and do step 4 (and then step 5 again).

Step 4: Sizing the model

 

Quote

 

Now we need to get it to really precisely line up.  Import Vita's head (hash 0f1f571d, #000067 in my frame dump).  We are going to attach the neck to the head, vertex by vertex.  Turn on Snap To mode (it's the magnet icon at the very top center of the screen, just below the tabs).  Click the dropdown next to magnet, and set to Vertex.  Now when you move one vertex, it'll snap to nearby vertices.

 

Spoiler

 

First put the head into Edit Mode, then put the donor body into Edit Mode.  Select the Move tool.

 

Spoiler

 

Select a vertex, and pull it to the adjacent vertex so that it snaps to the correct location.  ALWAYS MOVE THE BODY VERTEX!  Remember, we are NOT changing the head, it's not part of the mod!!  You will need to zoom in and out, sometimes look from the outside, sometimes look from inside the head.  Sometimes what looks like one vertex is actually two overlapping ones on the body - move them both to the corresponding vertex on the head.

 

Spoiler

 

Let's do the wrists next.  Move the hands into place (use face select, select all the faces {double check with delete and undo!!}, use the move tool to put the hand close but not exactly in place - you need enough gap to see what you're doing!).  Go into vertex select and pull the vertexes together, again from forearm to hand (modded mesh to native mesh)!  This time the hand is actually part of the mod so you could go in the other direction, but stretching the forearm is less noticeable.  Also, it's a good habit to build, some of the characters have separate hand meshes.
 

Spoiler

 

 

If you go into object mode, you'll notice seams since the vertices aren't connected.  Thus a seam will be noticeable in game even if the textures perfectly line up.

 

Spoiler

 

This isn't really an issue for now because the textures we use aren't anywhere near perfect, but let's fix this anyway in case one day we do fix the textures.

In edit mode select all the faces around the join.

 

Spoiler

 

Merge by distance (Press 'M' or go to Mesh -> Merge -> By Distance).  Tah dah!  No more seam!  (before texture is applied anyway)

Step 5: Exporting the model

 

Quote

 

This is the same as my other tutorials, but there are a few extra steps to replicating Switch608's magic.  First export "3DMigoto raw buffers" and save in a directory inside the Mods directory (preferably a new empty subfolder).

 

Spoiler

 

Copy my "vb_split.py" python script into the folder, and run it, it will split the vertex buffers and also create a skeleton .ini file for you.

 

Spoiler

 

Next copy over 00.dds and 01.dds from the Juna nude mod (or whichever mod you're using a donor).

 

Spoiler

 

Identify the Index Buffer hash and the Pixel Shader hash we'll be targetting.  Look in the frame dump folder.  Remember how my recipient mesh was #000069 (see the first few steps)?  Looking at the *IB* file for 0000069, I can see the IB and PS hash in the file name.

 

Spoiler

 

Now edit the .ini file.  In addition to removing the semicolons from the [TextureOverride] section and adding the hashes, we have to also add the texture map and normal map files (00.dds and 01.dds), and also get rid of the towel.  All the new additions are highlighted in red below.  Make sure the resource names match (the red arrows show the matching).

 

Spoiler

 

 

Load it up in game!  If you already have the game loaded, press F10 to reload all mods.  If everything went well, you should see your glorious new nude mod!

 

Spoiler

 

Want to change the breast size, or whatever?  I have a tutorial for that too!  https://www.loverslab.com/topic/166239-trails-of-cold-steel-4-mod-request/?do=findComment&comment=3757792

 

 

Congrats!  As always, if you like what you make, I hope you share with us.

 

Oh, and I usually don't share the final product of the tutorial (I want you to try it!), but how can I not share nude Vita?

@amorrow28 Fantastic tutorial, thank you. I had attempted to port Roselia before but couldn't get the weights right.

 

I transplanted Juna's body to Nadia. Probably took me around an hour overall. I'll sculpt it to better fit the body later.

 

I ran into some weight problems probably related to that left breast blob from Juna's mesh, but was able to fix it by hand.

I went ahead and did Roselia as well. The texture for Vita has some weirdness happening around the elbows; you can also see it in my Nadia image. I copied over the texture from Fie's folder and the problem is gone. No idea how the textures are different, but there you go.

If you are using @amorrow28's CS4_UnSkirtMod_v1.3a file, you can replace my file with one click. CS3 and Hajimari should modify the corresponding hash value, but you can try it out, remember to back it up?

So for some reason, after downloading this, several of the mods from your screenshots aren't appearing in my game.  Juna and Musse's Magical Girl outfits still have the whole skirts, Laura's swimsuit isn't changed, and neither is Emma's Butterfly Witch outfit.  Emma's default, Sara's outfits, and Juna's Resistance ones are working fine, though.

Very nice! Your work definitely makes it worth it for me to have made the tutorial. And I felt like I was going to die while putting it together. ? @Switch608, I have no idea how you did that TEN TIMES when you went from 4 characters to 14 all at once!

 

Also @coomi thank you for actually taking the picture of the stupid rogue vertex group in-game so people can see why it matters and why weight transfer can be so difficult. That happened with Vita, and I was so mad I just deleted and started over (after coming back hours later). By the end I wished I had taken a picture to show what happens, but I didn’t have the energy to go back and replicate that…

 

EDIT: Also for those who might think the rogue group is because of the mod, it’s not. That group is in Falcom’s original Juna model, thus Switch accounted for it in the nude mod.

Modding Roselia? Poor @Whayameen has already said he was done taking screenshots of the fairy spring scene, I feel like you’re just egging him on now… ?

did you install on top of the latest version of my mod? V1.3 adds a lot of shader overwrites on top of v1.2.
