@DevilMayCry You should be able to just overwrite the old models and everything should work fine. Projects using the old models will break. If you encounter any problems after spawning new animsets however, delete the /Jawsfm/Sonic/ folders and extract again.
hottest of hotfixes coming in: V2.1 makes it so her new lower teeth actually work!
both the "materials" and "models" folder in the archive go into the usermod folder. make sure no additional folders are created when unpacking.
@Gareth17 you can get a SFW version without these parts on the workshop: https://steamcommunity.com/sharedfiles/filedetails/?id=1282377168
No plans for an update. The textures work fine as long as the folder structure is not changed.
Update released that adds boob and nipple bones as well as a much smoother body (8k verts to 35k). Hope you're happy now.
Outfits are 50% completed and materials for the cycles version pretty much done. Mostly just missing a proper advanced rig now. And yeh, don't do that SFM to Blender thing, next to the mesh problems you also have lower res textures.
Unfortunately a flex can only move the mesh around, but not adjust its bone binding. This can't be fixed I'm afraid - if you need to rotate the spine a lot, try using the already lifted shirt bodygroup. Material overriding $iris did not work for me, but if it does for you, all the better.
Fixed the missing texture for the hair clip. Thanks for reporting! For the eye textures, just change the names of the 3 iris .vtf files. The texture with the name "GwenIris_dif.vtf" will show up in her eyes. reload materials or restart sfm for the changes to take effect.
This port is unrelated to any that came before it, so I don't know how they differ. My personal additions were anti-clipping flexes, clothes and weighting improvements. The hula set was not ported before IIRC. Other than that? No clue.
