I'm trying to make a chopping board, and so far I've added a hole using a bool, and then added a bevel using a mod. However, when I try to shade it smooth, these unneeded shadows are formed. How do I fix it so that the shadow isnt cutting across a flat surface like it would a normal cutting board?

shade flat shade smooth my topology

  • $\begingroup$ Blender is trying to smooth between faces that are perpendicular and it gives this bad result, if the Auto Smooth option doesn't work, try the Weighted Normal modifier, see here: blender.stackexchange.com/questions/258043/… $\endgroup$

  • $\begingroup$ the Weighted Normal modifier needs the Auto Smooth to be activated $\endgroup$

  • $\begingroup$ The top and bottom faces of your object are giant N'Gon's (faces with more than 4 vertices). Blender's shading system is based on quads (which then get triangulated for shading purposes). The shading artifact you are seeing is the result of a failed triangulation. Re-topologize your mesh so that all faces are quads. Or for a "cheaper" solution, try selecting the top and bottom faces and insetting them slightly. $\endgroup$ Mar 20, 2022 at 19:08
