I feel like I’m pretty close to having my vroid model ready to go for vrchat, but I hit a snag last night before I gave up and went to bed

I imported my model into blender, deleted meshes hidden under the model’s clothes/hair, decimated the hair meshes a bit, set up eye tracking and visemes, and then atlased the textures, exported as fpx, imported into Unity and... the model is not displayed in Unity at all, not in the preview window and not in the scene once I drag it into the workspace. Has anyone else run into this problem?

okay so NOW what's happened is that i disabled a bunch of shape keys that weren't doing anything, but i guess were breaking the model in some regard so disabling them and then re-exporting worked great

but the problem now is that though i can load the model into unity, there textures are nonexistent -- the entire model is just a single colour, and the material atlas in unity is just a solid off-white rather than how the model is actually supposed to look. did i like, not need to atlas the textures or
