loicseigland Posted July 4, 2018 Share Posted July 4, 2018 (edited) Hi, I hope I'm not asking a question with an obvious answer, please refer me to the relevant resource if there is one! I have a geometry which rests on a plane. After rendering with mantra, looking at the edges of the geometry which rests on top of the plane, these are looking strangely bright ( I've tried with different light sources, different samplings, etc...) I have recreated said issue with a basic box on top of a plane ( see attached images and hip file) The same issue still occurs if I move the box down, and make it intersect with the plane. If any relevant, this is with Houdini Indie 16.5.496, on Mac OS High Sierra 10.13.5 Am I missing anything obvious? Thanks in advance for any suggestion you guys might have! close_up_Active_Render.0001.0.exr higher_point_Active_Render.0001.0.exr funky_bright_edges.hiplc Edited July 5, 2018 by loicseigland Quote Link to comment Share on other sites More sharing options...
davpe Posted July 8, 2018 Share Posted July 8, 2018 hi, you're dealing with a very small scene. to get rid of the artifact either scale up the entire scene if you can do that or decrease Raytracing bias on Mantra node (this is sort of "more correct" but may take longer to render). cheers 1 Quote Link to comment Share on other sites More sharing options...
loicseigland Posted July 8, 2018 Author Share Posted July 8, 2018 Thank you so much @davpe, this was driving me crazy! Decreasing the Raytracing bias did the trick nicely... Thanks again for your help! Quote Link to comment Share on other sites More sharing options...
