    Default Unified Sampling

    Anyone know a setting for Unified Sampling to speed up FG & GI ?

    Read here for more info:

    Very helpful blog with some useful settings info. Bottom line, though, is that the settings seem very scene dependent.

    I do know that if you use Unified Sampling coupled with user_ibl_env or user_ibl_rect, you can use much less final gather.

    I've read that blog topic, I didn't gain to much info from it. I'll try the iBL(env/rect) nodes, use less FG bounces or remove FG altogether ? I'll try setting both.

    This explains why native ibl reduces the need for high quality FG settings.

    Unified "Quality" is scene dependent because scenes look different. We typically set the samples wide, min 1, max 250, and usually render to Quality 1.5 or 2.5 for production. Keep in mind that is using brute force techniques that makes it faster and Unified can decide where to place samples.
