I've managed to find a really nice model edit that is perfect for an avatar, but I lack the skills to create it myself.

This model has some tips on the site to help anyone work around it's small quirks, but should be reasonably fine to work with, as the only edits on this version of the model are a reshaping of her hips, thighs and butt. There was a comment about clipping somewhere, and the outfits did look a little too tight in blender, but that's nothing a little shrinking of the body can't fix.

This model should have both of her super suits included, but if not or something is missing, I have also linked an alternative model here just in-case, closer to the original model but not as "endowed". -> alternate asset source model

Whoever decides to work on this for me would be a living legend, but I have a few requests that I would like whoever makes this to target for the final unity project in somewhat priority order.

• Eye and Mouth Movement
• Physbones in the chest and rear (thighs too if you’re into it)
• Facial Expressions (on toggles in menu)
• Outfits (with material properties similar to the images on-site and the ability to wear nothing)
• GoGo-Loco
• You can add all that VRFury and SPS stuff if you want, but personally I won't be using it. If whoever make this wants to that's ok.

I don't think anyone has made a full port of this model and it's features to VRChat yet so you would be the first person to do this which is cool.

(I had to rewrite this post another time, removing some unnecessary filler text to streamline the post and to include some important information after I checked out the model files themselves.)
(this is the 5th rewrite at this point, I should relearn general literacy as a whole)
