Hopefully someone can help me with an issue that's been bugging me for a while now. When using Mental Ray to render out my games models, I've noticed that normal maps which had displayed exactly as I wanted them in the Maya viewport will be different, often dramatically so - harshly warped and not as expected.
I'm having to render them like this as a way to work around the transparency errors that Maya apparently has with my NVIDIA graphics card.
These screen grabs should show you what I mean. Maya viewport view on the left, Mental Ray render on the right. They're both using the exact same light setup but the render seems to be taking on the light in a different way...
