V-Ray Common batch render camera / 'renderable' flag problem

[jensl]

V-Ray doesn't seem to use the 'renderable' camera flag, and doesn't update when cameras are renamed. For example, we have a lighting scene that has a temporary camera and a primary camera, which is set as the batch render camera. Before rendering on a farm, the user sees the extra camera, deletes it, and properly names the primary camera. The problem is that once a camera is renamed V-Ray does not take note of this (Maya SW does, but does not display the changed name in render globals until the window is closed and re-opened).

I've tested this by duplicating cameras, renaming them, deleting them, and sending the batch render to the farm. I end up with blank frames and no camera-related error messages. I thought this might also be linked to renderable cameras, but I tested a batch render where no camera is set to renderable, even though it is set as the render camera in V-Ray common. This worked fine, and there were no related errors/warnings in the log about it.

Can this be fixed so that any time a camera is created, deleted, or re-named, the batch render camera (vraySettings.batchCamera) gets updated or runs a check? Using nightly from 08/17, but I'm quite confident V-Ray has worked this way a while.

Which Maya version is that? There was a problem with Maya 2011 where the list would not update. This is fixed, but even when it is working, you still need to close and re-open the Render Globals for the list to be updated (this is the case for all other renderers in Maya too).

Best regards,

Hi Vlado, this is with Maya 2009 x64.

I'm having almost the same problem with maya 2010 x64. Importing new camera, delete the old, rename the new to the same name as the old. The Camera name in the renderSettings list is being ignored at render time even though it matches the name of a camera in the scene. In our case the render hangs and the only other sign of a problem is a warning in the log about the camera FOV being zero. The problem persists through scene reloads and can only be fixed by selecting another camera from the drop-down list and then reselecting the original.
