Isleofgough Posted August 24, 2019 Share Posted August 24, 2019 (edited) I am rendering an image that takes about an hour and a half on a Imac 2017 and it has more grain than I would like (see attachment). How would I improve this without significantly increasing render time? My current Mantra render settings are: Mantra tile size 48 Reflection limit 4 Refraction limit 4 Diffuse limit 0 Color limit 3 Ray tracing Bias 0.001 Sampling pixel sample 5x5 Gamma 2.2 Min ray samples 2 max ray samples 8 noise level 0.001 Global quality 2 Diffuse quality 1 Render 16 bit integer Tiff with gamma 2.2, 2500x2000 px Edited August 24, 2019 by Isleofgough Quote Link to comment Share on other sites More sharing options...
Isleofgough Posted September 7, 2019 Author Share Posted September 7, 2019 It looks like "sheen" was what caused the problem. Changing it to zero fixed the render issue. Quote Link to comment Share on other sites More sharing options...
