UE4 Baking Mirrored Normals
In this video I show how to use Mudbox to cleanly bake normal maps for an asset with mirrored UVs for UE4 with no seams.
Please note I get all turned around when explaining "U1V1" vs "U2V1" and say the wrong axis. U is Horizontal and V is Vertical...that's all you need to truly know.
