I created this face in blender, it has smooth shading on but shadows in some areas appear sharp, I want the shadows to appear smooth consistently. Here's an example of the issue i'm having:

I'm not sure what i've done wrong, I'll happily supply the .blend file or any other additional information if needed upon request, Thanks! :D

  • $\begingroup$ Thanks for the suggestion Johan, but I have recalculated the normals and checked for any doubles but that doesn't seem to be the issue. $\endgroup$ – Gmate May 2 '18 at 23:06

What you're most likely experiencing is cycles not being able to shade properly on such a lowpoly mesh.

Some things that could fix this are:

  • Adding a Subsurf modifier to your mesh can smooth it out and remove some artifacting.

  • Having Auto Smooth in Data >> Normals unticked or set to 180 can remove unwanted sharp edges.

  • Increasing the size of you sun lamp also smooths out the shading.

  • $\begingroup$ Thank you, this does appear to be what the issue was, I ended up just adding extra geometry to the areas with shading defects and that worked perfectly thank you! $\endgroup$ – Gmate Sep 18 '18 at 20:17
