Francisco Penaloza Posted April 7, 2016 Share Posted April 7, 2016 Massimiliano, If you are learning VRay, I will recommend to not go and click in all the controls that VRay offers you. Most of the time, the preset that come with the software works fine. Like 80% of the time. You only need to place enough light in your scene and adjust your exposure, read and understand color mapping controls. you should get decent images. From your screen shot, your problem is only samples in your Irradiance. But you already move too many others values, so do yourself a favor and use any interior preset. if those splotches still there, increase the interpolation value in your Irradiance map, you are suing 75 dubdivs now and 25 interpolation. Increase your interpolation to something like 60, with default values and only changing that all those splotches should be gone. You'll lose some detail in the soft shadows, if that borders you then you need to use a higher Irradiance preset. or activate detail enhancement. best luck.

massimilianomazzini Posted April 9, 2016 Author Share Posted April 9, 2016 (edited) thanks a lot for your answer... the problem is with default settings i incur in un-acceptable sparkles (noise) level...therefore I'd need to AT LEAST tweak the interpolation (for the splotches) AND the noise and color threshold... i did put both at 0.05 and it looks like working fine (no more sparkles)...it just takes forever to render a simple kitchen... can you suggest me better values?

andrewmunene Posted April 9, 2016 Share Posted April 9, 2016 you can use the bruteforce render setup which will eliminate all splotches but increase render times significantly. Alternatively, render an irradiance map & lightcache for each frame, and test the results Link to comment Share on other sites More sharing options...
