Mental Ray compressing materials

[Anonymous]

Hi!

I'm using Maya 2015 and have this problem since the begining. The problem is that mental ray don't show materials properly in render view. This is the warning:

IMG  0.3    195 MB warn   102002: type rgba_h not supported by iff format, using default type rgba

All materials seems to be compressed, even I use lamberts and phongs (and one my own textured material). No problem in maya software engine. I tried to fixed it using steps form here: http://forums.autodesk.com/t5/shading-lighting-and-rendering/warning-mayatomr-scene-output-data-type... but nothing helped, only when I change in image format or quality there is another warning (like 5 looking like: PHEN 0.9     96 MB warn : Color Mgt: Only support RGB & A), but the result is the same. Any ideas how to fix it?

Ok, found the solution, it was a case of exporting materials into jpegs.

I've come to kind of solution, but I don't know which one worked and I'm to afraid to ask at this point. So, if someone will be in trouble:
- clean registry
- run maya as administrator
- changed all layers from reference to without flag.

Wish it will help you.
