Set fixed render time I have a question ragarding cycles. I want to render images with different settings (materials, sampling, etc.),
so I can compare differences afterwards. 

So I would like to limit the render time to a fixed time for each render (f.ex, 10 minutes for each file) - but I cannot find where to set render time anywhere. Where can I set a limit to rendering time?
It is not possible to limit the render time exactly. You must experiment with the number of samples to get an equal render time.
