issues of the day

I have one Quadro CX and one GTX260.

It's really difficult to sync these two boards. Sometime works, sometime don't.

Sometime the scene is completely white, if I use only the Quadro CX board the render is ok.

After having renderized with Vray RT GPU I'm not able to shut down 3ds Max (2010), I have to close it through the task manager.

Sometime with one single GPU all the scene is overexposed. I close Max, reopen it and it's ok.

There is a problem with fog. I have some glass elements in the scene with 0,01 meter thickness. With Vray legacy the render is ok, glasses are blue. With GPU glasses are black.

Sometime when I shut off the vray sun it stay on.

If I use Vray RT like production render is impossible to find the vraysky texture. So I have to switch in Vray classic mode, then Vray RT losing all the parameters.

Please repair Vray RT GPU, it's a little bit buggy.

Best regards.

another issue
Vray RT GPU in production render doesn't support alpha through transparent objects....

another new issue:

if I put 0 in the max path per pixel and 60 minutes in the max render time Vray RT GPU should render for 60 minutes, on the contrary Vray RT automatically puts 64 (path per pixel) and it renders for few minutes.

issue #4

If I choose stereo render (anaglyph) like production render, Vray RT GPU opens a new useless window.

I have a GTX 260 and I ran into memory issues sometimes. In the case of memory issues I had to restart 3dsmax and it was generally a pain and rendering behavior was hard to manage. Not sure if that is part of your hardware difficulties but maybe the 260 is not strong enough for some scenes. Also vlado mentioned different architecture cards are not compatible to render at the same time, not sure if Quadro and 260 match, esp. with drivers.

Yes, infact I've ordered two Gainward Phantom with 3GB.
I understand that RT GPU is young and few user are using it like production render but I would like substitute now my renderfarm with gpus and use RT only.

cropping/placement doesn't work
