vray 3 progressive sampler DE черные ambient occlusion тени
charlyxxx, спасибо. это получаетсья universal settings, где количество семплов ненадо ставить выше 8 нигде. min shading rate 8 это делает
вот что разработчики пишут
Normally you would leave all subdivs anywhere at their default values. They won't have any effect anyways - the 100 AA subdivs will almost certainly override everything else. However, some speed can be gained by spending a bit more samples on the shading effects (glossy reflections, lights,GI, etc.) than on AA. You can do this either globally through the Min shading rate parameter, or by increasing the subdivs of individual effects beyond those of the AA sampler.
