While rendering from Maya it gives black or blank output. I don't know how to use maya but the person who is using it experiencing this problem in his PC. He can successfully render the same file in other PC somewhat having the same graphic card and memory which is 8 GB and core i 7. Network is also OK. The PC perform rendering function for 7-8 hours. In both PC maya version is same which is Maya 2012 64 bit with same vray version. I formatted the PC as well.
