Hi everybody. Very new here, and a lot of stuff to learn. I used Ueberenviromnent2 for a night scene with candle light - Indirect light with directionnal shadows. Intensity 100%. Intensity scale 100% and occlusion strength 100%. Color occlusion: black 0. The picture is saturated by a smooth “grain” effect. Do you now what is my mistake and on what parameter I should play in order to have a better render ? Thanks for the help.

You probably most need to increase the samples settings, but lowering the shading rate and max error may help too.

the grain could be coming from UberEnviroment as Richard mentions but if the UberEnviroment is set to a high quality and you still get some grain then lowering the Shading rate more in the Advanced Render settings will help. This also mighr help with learning UberEnviroment http://www.daz3d.com/forums/viewthread/5320/

Also I have never seen a HDRI to be good enough to use Directional Shadows so best opt for Occlusion with Soft Shadows.
