We have the same problem where Maya doesn’t wake up after the render is done.. It only seems to happen when you use Maya’s own renderView to select which camera to render from.
A workaround which seems to work for us most of the time, is to drag a small region in Maya’s renderView, just to make the VRay framebuffer render from the currect camera. After that we can render the full image without problem in the framebuffer.
Would it be possible to select which camera to render from inside VRay’s framebuffer, so you wouldn’t have to use Maya renderView at all?
Regads,
Jacob
