Here's a quick GIF showing some of the progress on the final slime mesh. You can see the following blendshapes in action in this preview: Mouth Closed, Mouth Suck, Eyes Closed, Vagina Spread, Asshole Spread, Boobs Size, Butt Size*
The UV mapping and Texture has been heavily adjusted to accommodate the new mesh alterations, so the other slime colours and face textures will take a bit of extra time to implement, but it's not a huge setback.
*A note about 'Butt Size,' this is an experimental blendshape. Butt size would either be tied to Boob Size, or rather use the Penis Size DNA, which occurs in all monsters, but only shows up on males. This blendshape would give some function to the Penis Size DNA variable on female models. Still playing around with this idea, might not implement it ultimately.
