Yeah, these ones are hard to walk away from. NetEase really did good on these skins.

 

Like, people went out of their way to buy the Luna skin instead of just doing the event; they just purchased their way through it.

 

And Psy is going to sell like crazy.

It's much more simple actually.

Don't create the pak file with Unreal Engine, you don't need it, and you don't need chunks nor iostore. Just cook the content. Then create a new directory for the mod, give it a name like namemod_9999999_P and put there all the cooked assets. You will find all of them inside the project directory\Saved\Cooked\Windows (if you are using Windows).

Then drag and drop the directory of in the RepakGUI. Enable the option "fix mesh" and everything is done. You will have the 3 files for the mod: the pak, the ucas and the utoc. Done

 

How to avoid crashes with Repak:

Only fresh cooked meshes must be fixed, and only the first time. If you just edit something else like materials, textures or animblueprints, you don't need to refix, just repak it normally.

After you fix a mesh the first time with the Repak, in the root directory of the mod you will find a file called "patched_files". It saves all the meshes files fixed so they won't be fixed again.

If you update the mesh with a new one, just remove the file name from the list inside the file "patched_files" and recheck the flag "fix mesh" inside the repakGUI.

Only fresh cooked meshes must be fixed.

I hope my explanation is enough clear. If not, ask freely

 

 

Yeah I've tried packing the loose cooked files in repakGUI, and it still just gives me a hard crash whenever I mouse over Mantis on the hero screen.

And like I said, I could put a single mesh in there, or a single texture, regardless of the contents if the game calls for that file it seems to just crash

 

My process has been: Cook in Unreal 5.3 -> Copy Mesh/Texture/ABP files into a mod folder for packing(retaining folder hierarchy ofc) -> Open repakGUI -> file -> Pack Folder -> Select the folder -> [x] Fix Mesh -> Install Mod

I'm not re-fixing any meshes and there's nothing in the folder except the files directly from my unreal cook folder when I pack it

All of my textures have "NoMipmaps" selected under Mip Gen Settings in unreal

As by your description the problem seems that you are putting in the mod meshes not fixed. Search for the file "patched_files" and delete it. If you already fixed a meshe, it's there for sure.

Hi everyone, I have a problem that I need to solve. My game crashes immediately when it starts. It was working fine the day before, but today I accidentally deleted all my mods. Then, when I reinstalled all mods and tried to start game, the game crashed directly. I'm not sure if it's because of a game update or some other issue. Please help me.

verify the game and make Shure that the UTOC Signature Bypass patch is located in C:\Programs\Epic Games\MarvelRivalsjKtnW\MarvelGame\Marvel\Binaries\Win64\ 

I also deleted my mods when I deleted the game and haven't played in like a month so I'm not Shure why it could be crashing unless files are missing or in staled something in the wrong way    hope this helps

The problem has been solved. Thank you very much. It seems that the game mistakenly deleted my Bypass patch and some normal files. After reinstalling the Bypass patch and verifying the game's integrity, I was able to enter the game normally.

This is my process (i really now that Ctrl+C and Ctrl+V doesn't have any visual but just know I copied 1020 from my cooked folder and pasted it over an empty 1020 folder in my mod folder) 
If something is wrong here let me know. Otherwise it might be my files or project (this is the same project i've had since season 0 after all, things might have changed since)

The procedure is correct. Then it must be something in the files. I will check your mod to see if there is an error. The file is the one you uploaded yesterday ?

That should be it. The files in that one are patched, would you like the unpatched ones?

Ok the problem is in the meshes. The file is too small. Something is missing.

If you have the original blend file, export the fbx with these settings (the "Selected Objects" is optional)

 

Then reimport the new file with these Unreal settings (if you recreate the skeleton and the physics asset is better, just to be sure)

 

 

Then do again all the modification of the materials/texture/abp and do the procedure to repak

Let me know if it works

[HongChina]

Hmm.
I wonder if its just the mesh, or the files in general. When I tried packing with different files a few days ago, I tried with just the meshes, and one with just the textures, and it all crashed regardless of what was actually packed. I'll try reimporting everything. If something is screwed with the assets themselves it might explain why I've had issues with assigning chunks in the editor. (for what its worth, the crash dialog points to a texture when i have everything packed together)
If reimporting doesn't change anything, I'll make a new project and start from scratch and see if THAT does. The FBX should be fine, those are the settings I always export unreal meshes with, and they worked last year perfectly fine.

Wait wait wait
They changed to iostore packing didnt they?

So I'm going to have to package the project using chunks to separate out the girls now
And then run it through the repacker?

 

edit: and of course unreal is being a bitch and not working, can't assign things to chunks. 

is there a way to pak for iostore using a packer?

 

edit: alright its trying to load it now but now its crashing the game, mirae2099 luna snow mod works though so its something with my files

edit: tried to do it by packing the loose cooked files through the repackgui folder packer, still crashes. i guess i might actually need to go through and redo the mod entirely or something

 

I don't know how easy it is to troubleshoot issues but here if anyone wants to give figuring out what's wrong a shot:

Let me know if you encounter any issues.  I did this a while back and could redo it if you have any.   Far as I remember there's no lobby model.

Dude there has to be a better way to inflate boobs in blender.  The inflate tool is fine if you mask off the model but it ruins the nipples 99% of the time.

 

I have nowhere near enough knowledge in blender to find a way to select vertex groups for simple size modifiers so I'm sculpting everything and it's messy AF.

 

Any tips from anyone?  HatsuneSora makes some great boobs and I just have no idea how to work in blender to that degree.

[jacob the]

can someone make a futa/nude mod for mantis i don't care if its the smallest penis that a man can have, I

just want it

[HongChina]

Alright both reimporting and making a new project does nothing for the mesh. So back into Blender, I'll probably re-export the mesh from the game and use its armature on my nude edit (or redo it, I have a better body now)

The head normalmap for some reason still crashes the game with an error about file name address I think it was, but...
Other textures do work apparently. This is the small victory I needed to convince me to keep going

If you have a model with good rigging on the breasts, you can use the armature itself to scale them up, apply that armature modifier to the mesh (or save it, just remember to reset the pose after) and then use the sculpt tool after that to smooth it out until you get the look you're going for

This is awesome because this is the exact thing I'm looking for, but how would I do this?   What would I google to find a youtube that would cover properly selecting the vertexes/armature piece?   Thank you for explaining!

 

I can obviously turn on scaling by pressing S.  But I mean, how do I edit just the Breast portion of the armature?  Maybe my models don't have it since I exported them through FModel, but is there a way I can select the right areas and re-create those?   The armature does have vertex groups, but I don't know if they matter or not.

You'd be looking for bones attached to the breasts in pose mode and then scaling them up using the bone scaling
idk if there's any youtube tutorials for "how to make your characters tits huge in blender" though 

how familiar are you with using blender
