We have a set of 8 bpp TIFF images which are designed to be an special kind of single-channel textures for our model. For some reasons we couldn’t import them into the Unity, no any texture import settings are work. There are messages in the Console:
“Could not create texture from .tiff: File could not be read”
At the same time our 24bpp TIFFs are exported just fine (e.g. normal maps).
To this time I could not find in Unity documentation any notes about TIFF import restrictions. So is this a bug or Unity actually doesn’t support 8 bpp TIFF ?
Thanks in advance!
PS Unity versions are 4.3.3 and 4.3.4
