if you dont use a texture on a model it just chooses a random texture
and downloadable custom modifiers as md3 would be nice
Then use it. What's the problem? It was intended to USE an actual texture, not to borrow it from floor or tile.
Since custom modifier is nothing but a bunch of primitives, you can literally build your own custom modifier in 3D software.
i cant figure out how to apply textures to an md3 file, it would be nicwe to be able to configure a a model and choose an image texture
Just put a PNG texture in Models folder and name it as as the model.
