After adding some dunes to my scene, I realized after rendering, it shows polygons as if they were deformed. I tried to "smooth shade" but it didn't work. I also tried to apply subdivision surface, tried with all layers up to x4 to make sure it goes away, but it still doesn't.

Take a look at the images below: enter image description here See all the polygon changes on top of the dunes?

How can I fix that?

  • Hi, unfortunately that doesn't work for me. It has a value between 0.00 and 1.00, and I tried them all and no changes, the distortion is still there. – user116153 Feb 03 '21 at 09:53
  • It kidna makes things worse because it creates polygons everywhere now, not as exacerbated as before, but it multiplies them – user116153 Feb 03 '21 at 09:57
  • HI! I found the solution to this, by going to Modifiers > Smooth > play with it and smooth it until it gets rid of the triangles. So, it wasn't a shadow issue, but rather a mesh issue. Thanks for the help though! I will accept the answer above as the answer to my question in order to close the thread. Thanks! – user116153 Feb 03 '21 at 10:08
  • When I saw your first image I was thinking it is a geometry, but since you said you used high subdiv I abandoned this thought. BTW The proper way would be to answer by your self :) and ask moderator to reopen, now it is referring to a wrong topic. Or ... rather than this "cirkus" may I ask you to delete your question? Thank you – vklidu Feb 03 '21 at 12:40
