demostenes Posted May 20, 2018 Share Posted May 20, 2018 (edited) My object is rendered properly in 3ds max, when I import into Unigine, it seems, like there is some tangent/normal issue, object has visible faces. I tried to import both with import tangent space off/on, I tried smoothing normals/flipping tangents via resource editor, I tried not to invert G channel for normal map, I ve tried to import via 3ds max export plugin, but nothing helps. I ve also tried to import in different engine and it is OK there. It looks almost like some issue in shader. I ve noticed this behaviour long time ago for some surfaces, but it was not as strong as in this case, so I ve ignored that. Source files are attached. It is original source, so for normal map you have to invert G channel, to have proper Y axis for Unigine. Edited June 27, 2018 by demostenes Link to comment
morbid Posted May 21, 2018 Share Posted May 21, 2018 Hello demostenes, yes, there's an issue with low-poly models due to the SSAO algorithm we use. You can turn off SSAO to check this. You can avoid artifacts by: Enabling Ray Tracing in Settings -> Render -> Global Illumination. This will require additional render settings tuning, you may want to check this article Adding more polygons to your model We have plans for SSAO improvements but can't say when will it be done.

demostenes Posted May 21, 2018 Author Share Posted May 21, 2018 (edited) Thanks for clarification. I have Tay Tracing enabled and tuning parametres did not help. Only turning cavity off worked. As workaround I turned of SSAO for this material and manually baked ambient oclussion. Maybe SSAO cavity could be material parametr, not only global. Edited May 21, 2018 by demostenes Link to comment
silent Posted June 7, 2018 Share Posted June 7, 2018 Should be better in upcoming 2.7.2 update (SSAO buffer): How to submit a good bug report --- FTP server for test scenes and user uploads: ftp://files.unigine.com user: upload password: 6xYkd6vLYWjpW6SN Link to comment
