Thank you.
I'm working on my first "for sale" model and texturing in substance painter. I wondered what is the more common normal map format when selling models? OpenGL or DirectX? Thanks.
Thank you.
Maya, Blender, Unity, Marmoset Y+
3Ds Max, Unreal, CryEngine Y-
Actually it is not about OpenGl vs DirectX but about how each software implemented their normal map green channel coordinates - Y+ vs Y-. Two software running on DirectX can have different implementations.
So, what is more common, Maya or Max, Unreal or Unity? You can include both, or just one and leave a note for less experienced users like - normal map generated as -Y (DirectX), +Y (OpenGL) or something like this. Most software have a button for "invert green channel" anyway so it does not matter much what you are going to include.
