nigelgardiner Posted October 14, 2017 Share Posted October 14, 2017 Hi Nicolas Are you using nested dielectrics here? If so try reducing the ray tracing bias (Rendering/Shading) on the render node. I've seen similar patterns appear when liquid intersects a thin glass wall when using nested dielectrics and that did the trick. If not you could try - increasing the refract and/or reflect limits (render out the image planes to see which if either is the issue). -if that works but increases your render times by too much, switch at ray limit to - use direct lighting as background color. Hope that helps in some way. cheers Nigel. Quote Link to comment Share on other sites More sharing options...
Atom Posted October 14, 2017 Share Posted October 14, 2017 I might guess that black color is the reflection of a black sky. Try surrounding your scene with a skysphere. Drop in an HDRi or Angular map. Quote Link to comment Share on other sites More sharing options...
nigelgardiner Posted October 14, 2017 Share Posted October 14, 2017 @Atom If it was a black sky wouldn't be seeing similar artifacts on the crest of the wave created by the log rolling thru the water at some point? Hard to say without seeing the hip setup i guess. Quote Link to comment Share on other sites More sharing options...
