Looks hella sexy to me.
I'm not doing anything with this anymore. I have completely abandoned it. Anybody is free to do anything they want with it.
This has .DMX which is a session file, not a model. You get both of those Toriel models, and then put this .DMX in C:\Program Files (x86)\Steam\steamapps\common\SourceFilmmaker\game\usermod\elements\sessions.
You open it up as a session, not spawning a model.
What, don't you people want a THICK goat mommy?
I have already said these before, but here we go again.
No, I will not fix or do anything with this model. You have to either find someone who will, or you know, learn to do it yourself.
This model was made to be used for Blender/Maya, not for SFM/Gmod.
There are limits on how many bones and materials one model can have in SFM, so they have to be broken down into multiple models. So you just have to deal with it.
Try updating 7z or whatever you use.
After you have zeroed the clothes, select all the cloth bones that aren't locked and use the Default slider.
