Thanks for the response! I use Vray with standard material. The problem started with DISP map and when I changed to normal map the issue was less intense. I divided the face inside the group even rebuilted a few times, set edge length to 2. I will try to increase the quality of the image but I am not sure it would be a good idea. I use LIGHT CACHE 2000 subdivs and IR map min -1 max 1. I have encountered the same issue with a concrete floor material but the problem was resolved once I divided the face. This is more persistent.

Hello to all! I know displacement is an issue that has been covered extensively in this forum. I have read most threads but still I have an issue with my render. It is a brick material and I use normal map because I realised normal maps behave better in terms of displacement. I have grouped the faces together it seams fine in most of the wall but as you can see between the two windows there is an area with strange lines. I imagine it's the geometry and displacement map failure but I can't get rid of it. Is it a GI matter OR AA? Any thoughts? thank you in advance
