Change your primary method to QMC and render a small zone. The render will probably take longer and be more grainy. If the blotches disappear you know that it was the Irradiance cache method that caused the issue. Switch back to Irradiance cache and start working with the Irradiance cache settings until you are happy. Or stay with the QMC if that renders an acceptable result in a reasonable time.&nbsp;</P> <P>If nothing changes when you change the primary method try different secondary methods to find what causes the blotches.</P> <P>&nbsp;</P> Mon, 15 Sep 2025 09:38:06 GMT Karl Wir_n 2025-09-15T09:38:06Z https://community.graphisoft.com/t5/Visualization/White-Blotches-in-Cinerender-Renderings/m-p/671912#M26549 <P>I know there was another topic with this title, However, I cannot respond to it. I am getting white blotches on surfaces in my renderings that are done with cinerender. I tried upping the environmental values as suggested in the other post, but they still have white blotches. I'm a trying to increase them more, however, I really have no idea what that is doing. Are there any other suggestions?</P> Fri, 01 Aug 2025 22:53:38 GMT https://community.graphisoft.com/t5/Visualization/White-Blotches-in-Cinerender-Renderings/m-p/671912#M26549 svpribyl 2025-08-01T22:53:38Z https://community.graphisoft.com/t5/Visualization/White-Blotches-in-Cinerender-Renderings/m-p/673941#M26564 <P>Does anyone have a suggestion for this please?</P> Tue, 19 Aug 2025 18:46:38 GMT https://community.graphisoft.com/t5/Visualization/White-Blotches-in-Cinerender-Renderings/m-p/673941#M26564 svpribyl 2025-08-19T18:46:38Z https://community.graphisoft.com/t5/Visualization/White-Blotches-in-Cinerender-Renderings/m-p/673971#M26565 <P>There is a setting for the number of light bounces, I think that helps.</P> Wed, 20 Aug 2025 02:10:17 GMT https://community.graphisoft.com/t5/Visualization/White-Blotches-in-Cinerender-Renderings/m-p/673971#M26565 Lingwisyer 2025-08-20T02:10:17Z https://community.graphisoft.com/t5/Visualization/White-Blotches-in-Cinerender-Renderings/m-p/675581#M26575 <P>Could you add some pictures and a screenshot of your render settings (detailed settings). Also if you are using the standard renderer or Redshift.</P> Wed, 03 Sep 2025 08:41:56 GMT https://community.graphisoft.com/t5/Visualization/White-Blotches-in-Cinerender-Renderings/m-p/675581#M26575 Karl Wir_n 2025-09-03T08:41:56Z https://community.graphisoft.com/t5/Visualization/White-Blotches-in-Cinerender-Renderings/m-p/676673#M26587 <P>I am using the Cinerender renderer.
