View Full Version : Brazil: How to use DOF combined with skylight most efficient?

When rendering a scene with Brazil using 'skylight' combined with 'depth of field' the renderingtime increases much and the picture gets quite grainy. The graininess (is that a real word?) can be redused by:
1- increasing the image samplerate,
2- increasing the DOF samplerate
or/and
3- increasing the GI shaderate

All these sollutions increase the rendertime, but which one is the most efficient?

Nvermind. With some toying around I found the perfect sollution myself.

Increasing GI samplerate doesn't reduce grains at all.
Increasing Image samplerate helps but the rendertime increases also a lot (at least x4.)
Increasing DOF samplerate does the trick. Twice the amount of DOF samples gives a clear picture and the rendertime only doubles.
