Quote from DejavoDoes anyone know why my normal map-gradients gets squashed in compression by vtfedit? I import the file with ABGR8888. You can see the jagged gradient in the first pic top left.
I dont know if it makes a difference (infact I just tested and couldn't notice a difference upon importing/comparing both) but I always used BGR888/BGRA8888 for uncompressed textures in Source. Also check your texture flags; there are a few for filtering and one for specifying the vtf as a normal map.
EDIT: I did another test this evening on a normal-mapped model for CSGO and didn't have any issues with the normal map flag ticked, with either ABGR or BGRA (versus obvious compression with DXT5).
