Sonic feminina nua está pronta agora.

Não consegui consertar a textura do corpo que não mudou de amarelo para azul em 1 cena.

Esta é a primeira vez que faço um mod de troca de modelos para este jogo.

Não sei como as coisas funcionam.

Encontrei alguns problemas. Levei horas para descobrir tudo sozinho.

Não recebi ajuda de ninguém.

Olá GooseVis29, obrigado por sugerir o HEIO.

Estou feliz que tudo funcionou, exceto uma cena.

Decidi gravar 2 vídeos e editá-los em 1 vídeo.

Gravei Super Female Sonic com a textura do corpo amarela e Super Female Sonic com a textura do corpo azul.

Recortei a parte que mostra a Sonic Feminina com a textura do corpo amarela e mostrei a parte com a textura do corpo azul.

Aproveite o mod e divirta-se.

Just curious to ask. How is the Blaze nude for unleashed coming along? it looked awesome tbh

[Rokabur]

Just came to my mind, I'm guessing that all of the character mods for Unleashed don't change the Werehog (in the case of Blaze, a Werecat) since it would be more difficult to create a mod for?

Yes, it would be more difficult to create mods for the Werehog. I have no experience in modding characters over the Werehog. If I tried to do it, I might run into problems. I haven't learned how to do Werehog mods yet.

Was just curious since it just popped into my head. Would be interesting if it ever happens seeing all the different characters with a were form.

Hi everyone, Topless Blaze the Cat Firey Passion dx is here. It's a remake of the original mod by thelewdsonicmodder. While playing his mod, but it was very incomplete and buggy, so I decided to remake it with different sprites and animations. This is the first version, and I'll continue adding and fixing things in future updates.

How come Rouge gets a nude mod and all the other females are just topless?

It's pretty interesting to me because if I were to nudify a female character's sprite sheet, I would bare their legs and add a cute little slit in between first because that's so much easier than drawing a pair of boobs and having them jiggle naturally in animation.

 

I did find a few sprites of Blaze in her birthday suit though:

Hahaha, I was planning on adding more naked sprites, but I think that would break the idea of being a remake of the original mod.

And I just added those for fun :]

Because Rouge has the most potential in nude sprites. There wouldn't be much point since it's only like two pixels that cover the pussy area.

The only thing "special" about her is that Rouge is the most voluptuous-looking character out of the female cast but even so, I don't see how that should mean she can be the only one who gets to be naked like the male cast can. Like who cares if we could only see like one or two pixels of pussy (which also applies to Rouge by the way, it's a vulva for crying out loud) if we could still see the other Sonic girls' entire colourful bodies completely bare?

Their boobs may not be as big as Rouge's but not all of us care that much about breast size.

 

If I have the time and patience to edit an entire sprite sheet from Sonic Mania or Sonic 3 AIR, I would totally do nude edits of Blaze the Cat (or Amy for Origins).

However, unlike those topless edits, I will take account of that random fun fact about Blaze being insecure of her small chest so there's that:

The first reason I decided to go full nude with Rouge was because it wasn't that much more work, as everything that would be black just needed to be skin instead, whereas Blaze would need a lot more attention, even if it was just removing the pants or whatever. The second reason is because she at least has a noticeable butt when she's on a rotating device or monkey bars, also during Blue Sphere stages. Most other characters aren't thicc enough to have one that's noticeable.

I like Blaze a lot more than Rouge AND prefer smaller breasts over beach balls.

I love that idea and I also support your opinion, as I said before Blaze is topless because the idea was to make a remake of thelewdsonicmodder's mod but if I have enough time I will make a nude version

 

But for now I have to finish the Sally Acorn mod that I've been putting off for a long time.

I haven't given up yet.

In fact, I just figured out how to fix the model's textures in-game!

 

 

It turns out that the textures weren't in the correct format. I was just going by the default settings when converting them with NitroPainter.

I didn't realise this until I randomly decided to plop "blz.nsbmd" to NitroPainter's window and checked out "VRAM Use".

Blaze's model textures are meant to be formatted as "palette16" while 3/4 of her Axel Jump model's textures are formatted as "a3i5".

 

 

So I made another attempt at modding the game but this time, I simply replaced the textures with the NSFW versions that are now correctly formatted for Blaze's model (.nsbmd) in an unmodified .nds rom. No reimporting models, just good old texture replacing.

 

This is what will happen if there's even at least one texture in the incorrect format seen in the screencap above that said "tex4x4".

The result is that Blaze's model will be fully untextured:

 

This is what it looks like if all textures including the custom ones are in the correct format:

 

So close to looking good but unfortunately, the skirt of her coat remains and the UV mapping of her gloves needs to be moved.

 

There could be a bottomless mod so the skirt looks less jarring if Blaze is still wearing her coat, but parts of her gloves will still have the wrong colour and, although it'd be subtle in-game, the bottom of her crotch won't show her pussy and butthole, and instead displays a solid purple colour due to the original UV mapping being scrambled around the edited area of the texture.

 

 

I could fix both of these problems but that requires importing the model with the removed skirt and fixed UV mapping, and I haven't found a way to do that properly that won't break the animations as you can can see for the screenshots below:

 

 

But hey, at least the imported model is properly textured this time and I can confirm that Sonic's textures when playing as him is also no longer affected.

Now I just need to look into getting the animations working... the next time I decide to dedicate time on it that is.

 

So I've returned to my attempts of making the Nude Blaze mod for Sonic Rush a reality but this time, I think I know what's going on.

The Nintendo Nitro System Blender Plugin (NNS-Blender-Plugin) mucked up the model's bone hierarchy which means if the model's bones don't completely match what the animation file (.nsbca) expects, it'll mess up the animations or cause crashes.

 

I know it's the plugin's fault because whenever I export the model, it always adds two additional bones (root_scene and Armature) that never existed in the original model and thus it ruins the order and hierarchy of the bones. I heard this is necessary for making model imports for Mario Kart DS but when we're forced to have those unnecessary bones, the plugin is effectively useless for modding other DS games. I've seen this issue happened to people trying to model import for Nintendogs and New Super Mario Bros where the imported models were seen to also have ruined animations due to bad bone hierarchy which is very similar to my Blaze's model's problem.

If there's an option for the plugin to not add those bones when exporting, model importing for DS games wouldn't have been hold back.

 

So what can I do?

From what I noticed, Apicula won't play the animations for the nude Blaze model (.nsbmd) if it's paired with the original animation file (.nsbca), but it does if I replaced the latter with my own .nsbca file after exporting and merging the animations from Blender.

As you can see, the animations appear to be looking correct with no distortions because the exported animations now take the two additional bones into account.

So what I could do is export every animation from Blender and merge them altogether into one .nsbca file and have that replace the original file, right?

Well unfortunately, that leads to another problem.

 

Whenever I export an animation from Blender, it comes out as a singular .ica file. I have to manually export every animation to produce an .ica file for each. As tedious as that sounds, that's not really the problem. The problem is whenever I try to merge like more than 50 .ica files with g3dcvtr, it produces an error so the .nsbca file won't be made. 

The original .nsbca file contains 80 animations. If I can't merge that many .ica files into one .nsbca file, there's going to be problems in-game (crashing) if half of the animations don't exist once I replace that file.

 

At least I got ourselves a T-posing naked Blaze in-game:

 

So what else could I do?

Apparently, there's a Nintendo Nitro System plugin for an old version of Maya (2011, I think).

It's going to be tedious having to find a copy of an early version of Maya and learning how it works but this might be my best bet on getting my mod to work.

If that plugin allows me to export my edited model without ruining its bone hierarchy so I don't have to modify the animation file too, I might be able to finally have a functioning nude Blaze mod for Sonic Rush (and then Sonic Rush Adventure)!

If that plugin allows me to export my edited model without ruining its bone hierarchy so I don't have to modify the animation file too, I might be able to finally have a functioning nude Blaze mod for Sonic Rush (and then Sonic Rush Adventure)!

It turns out there's a way to remove the additional bones from the exported .imd model file from Blender by simply editing it with a text editor.

Left is the edited file, right is the original version.

It's very important to have the values of each node's parent, child, brother_next, and brother_prev correct or g3dcvtr, the tool used to convert the file into a .nsbmd, will have an "Unknown exception" error. So after I corrected the values after removing the top two unnecessary nodes/bones, I was able to convert the file.

 

Remember when I said that Apicula won't have the exported model (.nsbmd) use the game's original animation file (.nsbca) due to having too many bones?

Well, with those bones edited out, my edited model was able to be paired with that which means it can now use the animations.

Except it's still broken... It's no better than when I tested my imported model in-game which also had the same animation issues.

The only thing I accomplished is that I could test the model's animation with Apicula now so I don't have to test in-game every time.

 

My theory is that my exported model's bone hierarchy is different to how the original model set it up.

I'm not sure if this is the fault of the NNS-blender-plugin or Apicula changed it when I converted the original .nsbmd model into a .dae/.glb file so I could import it to Blender. If it's the latter, that's a problem. Exporting the model with Maya would be pointless if it's going to have the same incorrect bone hierarchy so forget that idea.

However, I don't know any other tools that can convert .nsbmd models into a file that can be imported into Blender. Apicula might be the only one.

 

The only thing I could do is try manually change the order of the nodes of my .imd file.

The left list is the node order of the original model.

The right list is my edited model with the incorrect order of nodes.

I'm not sure if it'll work but changing my model's node order to match the original order might be my best bet.

So I tried to change the order in the .imd file and making sure that each node's parent, child, brother_next, and brother_prev values are correct.

But unfortunately, no matter how hard I tried to correct something, g3dcvtr won't let me produce an .nsbmd file out of my .imd file.

Usually if something's wrong, it would produce an "Unknown exception" error.

But for some reason after I changed the node order, g3dcvtr has this error instead:

If I can't find a way to get around this issue, even with every node having the correct parent, child, brother_next, and brother_prev values, I don't know what else I could do.

Man, you've really outdone yourself. I'd say, you've taken the mantle from thelewsonicmodder awhile ago and done great work with it. Glad you're getting back on the Sally one too. I remember bothering you about it awhile back lol. Nice to see you return though.
