What I did was I made the basic model in VRoid, then, I used blender with CATS Blender plugin to get the model into blender. Once it was in Blender, I made a few new blendshapes by first converting the triangles into quads, using the “merge by distance” function to fill in any holes, then I began using sculpt to add new blendshapes. Using sculpt in blender can be a bit tricky, so definitely take some time to get acquainted with the sculpt tool. For this particular model, I used the “blend from shape” function to add the fat blendshape I had made with the basis key. That way she is always big. I then put the model into Unity, where I have a converter to put the model back into VRM format. I followed a tutorial to make sure everything worked. Of all my previous models, this one has some of my favorite features. I created an emission mask to make sure only the clothes, eyes, and the ends of her hair would glow. Once the model was back in VRM format, I simply uploaded it here.
