Hi guys,
When I render an object, which is very small in the camera (a character with aiToon), it takes 3 seconds for Arnold to render, but around 60 seconds to render the blackness around it.
It is a Render Setup layer, with Visibility - Camera set to 0 (so the environment is there, but it's not visible).
How can I speed this up? What should I do to make Arnold ignore it altogether?
