PTex as bump map?

[YoyoBoy]

I can't seem to get a Mudbox-created Ptex file to work as a bump or normal map in VRay 2.4. It works just fine as a displacement map, but I'm trying to cut down on render time.

Thanks.

and if you stick it in a VRayColor2Bump 1st?

Hm, this worked the last time I tried it (for bump map at least). Can you post the scene or send it to me at vlado@chaosgroup.com ?

Best regards,
