3 questions about: render region, file postfix and real color pass

[iLuso]

Hi guys!
I have 3 simple questions!
1) how I can disable render region by python?
2) how I can render images with out '_tmp' postfix?
3) how I can render images with out Real_color pass?

1) how I can disable render region by python?

You have to wrap the mel into python and use the vray vfbControl command. This should work:

maya.mel.eval('vray vfbControl -setregion reset')

You can run the vray vfbControl in MEL to see the help for it.

2) how I can render images with out '_tmp' postfix?

The _tmp suffix is always added when you're rendering single frames from within Maya's GUI. The suffix will not be added if you're rendering animation from the GUI or rendering in batch mode.

3) how I can render images with out Real_color pass?

The Real_color channel is always added when you're rendering with stereoscopic cameras. I'm not sure if there's a way to disable it, but I'll check.

It works! Thanks!

Ok, but if I export animation in vrscene from GUI it added.

Thanks for the hint!

Yes, it also adds the _tmp to the output file with vrscene. It's the way it works. You can use post-translate scene access to remove this from the output file name, actually. https://docs.chaosgroup.com/display/...ed+V-Ray+Scene
I could do a test with an example script.

We're looking into whether the Real Color should always be written out, I'll let you know what we find.

VRay will not attempt to write the RealColor channel anymore when rendering stereo images if shade map export is not enabled. This is now part of the 3.6 stable nightlies and will be in the next major release.

Great news. Thanks Yolov!
