Hey !

I have a character model with 5 different uv maps on it imported directly from Blender with a .blend file. I get this warning for each material on the model, and also some materials are weirdly enough duplicated, these are the warnings/errors I get in the console:

'.' is not a valid texture file name on asset 'Assets/Imported Prefabs/Character (3).blend' on material 'HeadMaterial' of renderer 'MainCharacter'. The file will be ignored.
'.' is not a valid texture file name on asset 'Assets/Imported Prefabs/Character (3).blend' on material 'C2FaceMaterial__Untitled_003' of renderer 'MainCharacter'. The file will be ignored.
'.' is not a valid texture file name on asset 'Assets/Imported Prefabs/Character (3).blend' on material 'C2ShirtMaterial__Untitled' of renderer 'MainCharacter'. The file will be ignored.
'.' is not a valid texture file name on asset 'Assets/Imported Prefabs/Character (3).blend' on material 'C2ShirtMaterial__Untitled_006' of renderer 'MainCharacter'. The file will be ignored

These are just a few, it’s at least 5 more warnings/errors.
Any help is highly appreciated!

For anyone who searches this answer in the future.

Having examined the blender file the problem was that the model was using 5 uv map channels. 1 channel per material. By removing all but 1 channel and remapping the error was removed.
