Hello, I am using decals with a normal map to make foot prints in the snow. It works fine on a regular surface, however, on a landscape the normals (highs and lows) are inverted. Does anyone know why this is happening or what I can do to fix this? Thanks.
Hmmm… Decals probably shouldn’t care about the underlying normals. Are you using textures on the landscape you imported yourself? Might need to flip the green channel on the normal maps. Or flip it on the decal normals and other objects’ mats you may have imported? Some other 3d apps (like Blender) have the green channel of normals pointing in the opposite direction by default, so if unflipped in UE, they’ll basically be inside out.
