enter image description here Hello, I'm having an issue where the lines in my mesh appear after I add a bump map. I'm using a bump map on other meshes in the scene but this is the only one with a problem. it only appears in the render view. Any help would be much appreciated.

  • $\begingroup$ Hello and welcome to BSE! You need to provide more details about your shader setup. Can you also share your file? blend-exchange.com. Maybe this helps? blender.stackexchange.com/questions/91042/… There is also a known bug that could have caused this problem but I can't find the thread. Also see bug report projects.blender.org/blender/blender/issues/74367 $\endgroup$ Sep 21 at 8:56
  • $\begingroup$ Hi there! I've posted my shader setup! changing it to non colour doesn't seem to fix the issue. $\endgroup$

  • $\begingroup$ ben : Thanks for the edit. Unfortunately, it could well be the known issue which @HarryMcKenzie refers to, in which case we won't be able to help; your best route might be further subdivision of the mesh. Which isn't ideal. $\endgroup$
