Question about importing PBR textures from Substance Designer

(1/1)

gazarika:
I have a question about importing PBR textures from Substance Designer or in general
Substance Designer export textures like this

basecolor -> sRgb
roughness -> raw

at first the material did not look like the one in Substance Designer
to make the material looks exactly like in Substance Designer
I have to load the roughness bitmap with override Gamma = 1.0

now I'm a little bit confused! should I load every bitmap that will be used as roughness or bump with override Gamma = 1.0 in general?
or this is only for bitmaps saved with Substance Designer as raw?
and how could I know if a roughness bitmap needs to be Gamma corrected or can be loaded normally

James Vella:
All textures except the basecolor need to be gamma 1.0
