I created this model to practice creating Vtuber models.
But when I export and use it, I see that it has no textures.
I've watched videos and asked ChatGPT, but I can't find an answer to my problem.

These are the nodes I use for the mushroom and dress.
For the rest, I use the same one, just without the nodes below.

Blender doesn’t support VRAM 2.0, the plugin is outdated. You have to export to 1.0 vrm.

>>1014644
You can't use nodes if you're exporting outside of Blender, you need to bake into a texture (or recreate the shader inside of Unity but that's more complicated and doesn't respect the VRM format)

Well, I've managed to get some color, I guess now I'll fix things like the face and the dress.

The VRM plugin is particular about what shader it can export. It's usually either Principled or the Mtoon shader the plugin ships with(to Archive the cartoon look). And you can't use "node graph shaders"

Like using a voronoi texture, because that is a blender internal function.

You have the principled bsdf or mtoon shader, with regular textures as input. You can bake those "node graphs" in the bake section of cycles
