Cuenk89 Posted June 6, 2022 Share Posted June 6, 2022 Hi all, I have a Karma hair question. I'm using Hair Shader and a hdri light plus area light. What parameters may I have to tweak to get rid of noise? Now I have those parameters: Pixel Samples 192 Min Ray Samples 1 Max Ray Samples 9 Light Sampling Quality 4 The rest as default I tried Pixel Samples 256 and Max Ray Samples 32 but rendertime escalates drastically, also rendered at higher resolution with lower samples. Is there any parameter I'm missing or any more optimized way? Thanks in advance Quote Link to comment Share on other sites More sharing options...
Atom Posted June 6, 2022 Share Posted June 6, 2022 I haven't test it with hair yet, but under Image Output/Filters you can enable Denoising. I'm not sure what effect denoise has on thin hairs. Also try another HDRi image if you're using one. Some of them tend to produce noise. It's not unheard of to blur the hdri map to obtain smoother results. 2 Quote Link to comment Share on other sites More sharing options...
