Accessing PyMel function during VRAY Post Translate Python causes render failure

[temp_design]

Hi,

We've been experiencing an issue on our render farm when trying to access PyMel functions from within the VRAY Post Translate Python script. The problem only seems to occur when Maya is running in non-gui mode. Everything seems fine in the log but then:

[2012/Mar/9|12:41:43] V-Ray error: There was a fatal error rendering the scene.
Error: There was a fatal error rendering the scene.

If I don't use PyMel everything renders fine. Is this a known issue? Is there a workaround?

Which V-Ray version is this?

Best regards,
Vlado

Ok then; can you get me more specific reproduction steps? V-Ray seems to run fine through pymel in general; not sure about the post-translate python callback though - what kind of code do you try to execute there?

Best regards,

To reproduce the issue you just need to make any simple Vray test scene. Put the following code in the post-translate python box:

import pymel.core as pm

AllObjects = pm.ls("*")

print AllObjects

and then render the scene using render.exe

The pymel code will run perfectly fine, but the render fails in the manner described:

V-Ray error: There was a fatal error rendering the scene.

Thanks, looking into it now.
