I’m trying to understand Epic skin shader setup using the provided example scene (Content Examples → Skin Rendering level).
I noticed that pores mask that Epic uses does not match pores noraml and roughness map. Pores mask seems to be the same texture, but it is offset in strange way.
Here are the few pictures to illustrate my point:
Google Drive: Sign-in if you switch from normal to roughness, you can clearly see that they align. But when you switch from normal to pores mask, you can see that they are mismatched. I included an image where i overlay mask over normal and show strange way they are mismatched.
Also, if you make pores really large, and give them distinct color (color uses pores mask, while “making them large” means messing with normal map) you can clearly see on the model that color are not matching pores closely.
My question: is this intentional? What purpose it serves? Or it is an error and was not intended?
