DirectX vs. OpenGL normal maps I'm curious which type of normal map works better? DirectX or OpenGL normal maps? Which one to use for cycles and eevee?
Only DirectX applications use DX normal maps. And DirectX run only under Windows mainly due to license. For everything else you need to use OpenGL. For sure is good always check documentation.
