If you would like to use the rotation feature without breaking the tangents and normal maps, use the Mesh Import Rotation Tangents Fix mod.įor regular assets such as buildings, props, vehicles, trees, and citizens, the normal map works correctly with no inverted channels, according to the standard described above. The rotation feature in the asset editor mesh importer is broken - it produces incorrect tangents, which will make normal maps appear incorrectly or not at all depending on the orientation and uv mapping of each face. That means it appears to be lit from the positive x and y directions which is the normal map standard.
Some normal map generators have settings for inverting the red(x) and green(y) channels, but some of them invert the red channel by default.Ī regular normal map with no inversions looks as if it's lit from the top right - that means the red channel looks as if it's lit from the right, but the green channel looks as if it's lit from the top.

The letters are supposed to look extruded in this example.īefore you decide if you need to invert one of the normal map channels, you need to make sure the normal map generator you are using isn't inverting it by default.
