Hi All.
So basically I plug in a displacement map into a shader, assign to object and when I go to render in mental ray production quality preset settings it begins the render process but then stops within a couple of seconds and says render complete without actually having done anything apart from creating a 1kb image file extension.
I've tried 8bit and 32bit tif displacement map as well as an openEXR. The maps look fine.
I've tested with a simple sphere with quick displacement. If I remove the displacement then mental ray renders fine.
This is using maya 2009, also tried in 2008. Disp map created in mudbox 2010.
Is there a certain setting somewhere that needs to be turned on!?.. I'm pretty sure this used to work before a few years ago so I doubt it's a hardware issue.
I'm really annoyed that it doesn't even want to start the render process at all!...
Any ideas?...
Thanks in advance.
