I have been banging my head against the wall for long enough that I feel I should get some clarification: we need to program/model the shapekeys ourselves, right? As in, not just put in Belly, Breasts, and Fat as shapekeys, but also manually manipulate the model so that it will acquire the desired shape, right? Just want to make sure I'm giving myself an aneurysm using Blender and VRoid for good reason, lol.
Also, to be super extra clear, you stressed the exact names for the shapekeys, and then also included those names in quotation marks. Are the quotation marks to be included as well (e.g. "Belly"), or are they actually meant to be input without quotation marks (e.g. Belly)?
Sorry for the silly questions!
