Coordinate System Setup
This is something I have always wondered about for years. In the Coordinate System Setup settings there are 3 options TS, LH, and RH. TS obviously is for Tangent Space, but what is LH, and RH? I don't see any reference to them in the manual.
My 3D software Lightwave uses. Y+ facing up X+ Z+ Far
TS uses Y+ facing down X+ Near Z+
LH uses Y+ facing up X+ Z+ Far
RH uses Y+ facing up X+ Near Z+
LH matches my coordinate system, but it generates a green normal map instead a purple normal map, so I always use TS and flip the Y and Z in my software. I've always wondered why I couldn't use LH since it's a match or use RH and flip the Z which is only flipping one coordinate vs the two that I have to flip using TS. The reason I don't use RH is I don't know what it means and have always assumed I needed to use Tangent Space maps.
