I’ve been using RGB channel packing for roughness, metal and AO textures with no compression issues. However, I’m trying to created some pattern masks in RGB (for a fabric texture), and the hard edged masks look horrible in-game due to the compression.
I’ve been reading online about UE’s compression issues and have found a lot of info, but no real conclusions. I’ve tried both PNG and TGA, every compression setting available in UE, as well as playing with compression quality (which didn’t seem to change anything?). All my experiments lead to the same artifacts.
Is there an actual solution to this or should I just load in my masks as separate texture files (which will greatly decrease the amount of variety I can include for my instances)?
