I have a script in Maya (python) that renders a series of frames to the V-ray frame buffer, one for each render layer. It is working well, but when switching render layers and launching the next render, Maya grabs focus, interrupting whatever task the artist had moved on to while the script was running. I would like this to be a background task. Maya is running on Windows.
