So if I’m understanding that post correctly:
Albedo is R/G/B channels on the _ar file.
Roughness is alpha on the _ar file.
Normal map is G/Alpha on the _no file.
Occlusion is blue on the _no file.
Paint is just hte red layer on the _pmg file.
Material is just green layer on the _pmg file.
Dirt is the blue on _pmg file.
Glow is the alpha on the _pmg file.
Do I have that right?
