Author Topic: UE4 workflow - Material color blend  (Read 3357 times)


Since UE4 likes to have roughness and metallic maps as RGB and not grayscale .tga files, how can I change the material color blend roughness and metallic values to be color rather than grayscale? With the standard setup right now, I always have to redo this step in Photoshop.


Changing those filters would be a very complicated process and counter intuitive as these maps should be greyscale anyway. What I do and what I would suggest is to export as greyscale png instead of tga as UE4 supports those.

Okay I'll export as .png then, thanks a lot!
