I am trying to model a snooker table for an Unity game and I have an issue with strange shadows on the cushion: enter image description here

This is how I modeled the curved edge: enter image description here

It's not an Unity issue because if I choose smooth shading on Blender, I get some strange behavior too: enter image description here

I tried to recalculate the normals and I also checked if the top vertices are on the same plane and they are. Am I modeling it wrong?

  • perhaps share this part of your object? https://blend-exchange.giantcowfilms.com/ – moonboots Jan 04 '19 at 22:37

  • This looks a little like the shading problem here https://blender.stackexchange.com/questions/126657/strange-shading-on-faces-in-blender-2-8/126664#126664 Try moving your lamp about or disable Shadow in the Light menu. – 3fingeredfrog Jan 05 '19 at 13:44
  • @3fingeredfrog I have no lights in the blender file. Moreover, the strange shading on my model occurs on a flat surface. – Bogdan C. Jan 05 '19 at 13:57

Sometimes you get this issue with orphaned vertices, which can be fixed with Merge By Distance option. And sometimes it needs to be UV reunwrapped, as I think you have discovered.

It seems I fixed it. I am still learning so I am not sure what fixed it but I: 1. applied the modifiers 2. removed UV Maps on all meshes on Object Data 3. exported to Unity 4. checked Generate Lightmap UVs box in asset imported in Unity

I think it was an issue with UV Maps.
