I’ve created my own SBSAR file in Substance Designer.
I imported SBSAR file into my Unreal project and when I import SBSAR file, only the base color and normal maps are imported correctly and other maps are imported as wrong format.
So, I would like to import my Roughness/Metallic map as Default format, including alpha channel but RM map is imported as grayscale format.
Odd thing is, I have exactly the same options for the output for base color map but other maps (RM Map, Opacity Map, AO map) are imported as grayscale, rather than default (RGBA) format.
Is there a way that I can solve this problem?
