Normal Maps

In 2022.2, we added Flip U and Flip V to switch the orientation of what is stored in the normal map on the axis, ensuring the bump map is uniform with the normals displayed along the U and Y axes. Find them in the Material Editor's Bump Texture section.

To fix the normal map's tangent vectors orientation, change one of these and see if it corrects the issue. If it doesn't, disable that option and enable the other, or Enable both Flip U and Flip V. These options enable VRED to support different kinds of normal maps, as they provide a solution for aligning the normals.

Incorrect with Flip U disabled Corrected with Flip U enabled
Note:

When using Flip U or Flip V for a normal map, the Parallax Intensity value should be kept at 0.0, as the height cannot be estimated in this case.
