Not sure if this is the right sub-forum, but it is a shader/rendering question, and it seems to fit here better than the Requests forum…
Basically I was wondering how I can set up Maya’s High Quality Rendering default viewport shader to have an option to flip the Y-axis of normal-maps. By default it displays them with Green = Y+, while our engine uses Green = Y-, so we have to use alternative shaders to get the normal-maps displaying appropriately in the viewport.
I’ve had a dig around the Maya program folder but can’t seem to find the shader that it’s using by default, and I can’t find any info on editing this stuff either online or in the Maya documentation.
I was having the same issue recently I am not sure if this sollution applies to all versions of Maya. But in 2008 if you select your mesh and go to the attribute editor there is a tangent space section in there switch the coordinate system to display left handed. This worked for me
It seems a bit strange that this is a mesh setting rather than a material setting, since that means I have to set it for all meshes using a material rather than just once per material.
I wonder if there’s a way of setting this globally by default, so all new objects created will use the “Left Handed” setting.
