I am trying to render a complex object (suppose this is a torus). The area occupied by the object itself is much smaller than the area of the object bounding rectangle. I only need to render this object.
The surrounding scene is not important to me (besides its effect on the object lighting). I try to adjust the object material and I often have to rerender the scene.
It takes a lot of time, so I want to throw out the rendering of all the excess. I know about rendering boundaries, but this only works for a rectangular area, which is not effective for a torus. Can I somehow define the rendering area including only interesting object?
My guess how I could do it:
- Disable some tiles during rendering.
- Determine the non-standard ray density distribution for tracing.
Unfortunately, I did not find the standard functions and plugins for this. Maybe someone has already solved a similar problem and knows the solution.
