Black render with Mental Ray IPR. #2

Closed richardlevene closed 11 years ago

richardlevene commented 11 years ago

When I try and test render using IPR I get a black render. My alpha appears but the rgb is black. When I do a normal render it is fine.

Using latest Stable 4.0.5 of GUI helper script with Mental Ray Standard 2.0.6 template.

Not sure what is causing the issue.

Thanks,

Richard

Hello Richard!

Unfortunately I'm not very surprised, the IPR only supports a subset of Mental Ray features, for instance connecting a simple mib_lookup_spherical shader to the camera doesn't work in the IPR. I don't really have any solutions for that, the ball is really in Autodesk hands although I'm not sure they are willing to do anything about it. It has been like that for years now.

Cheers,

Thomas

Hi Thomas,

Hmm ok. Yeah IPR support is pretty poor with mental ray. I do have Spraytrace and that works just fine so using that as my mr IPR replacement. Just wanted to see if my initial problem was just me or a universal issue.

Many thanks,

Richard

Yeah it's a shame because, Arnold or VRay works much better in that regard than MR. Softimage Mental Ray render region is very good also, probably the best Mental Ray integration to date.

Thanks for reporting the issue anyway!

Thomas
