  1. I get a flipped polygon after Cycles bake.

How to resolve it?

  1. When I apply the normal map I get the strange, sharp shadow on the border between dark side and light side of the cylinder.

Is it bad baking or very low polygon mesh?

How to improve it?

Link to .blend file if necessary:

After recalculating normal on the lowpoly mesh (Ctrl+N), and shading it smooth rather than flat, I found only one small error remained, and it was caused by the light, not the map. so here is the re-baked normal map, but if you see a really sharp contrasting shadow, it's a different problem.

  • $\begingroup$ Actually, I just did it without recalculating normal and it worked fine... weird. $\endgroup$ – Scalia Oct 12 '15 at 18:42
  • $\begingroup$ thank you, but I still can't get the correct normal mask. Can you please tell your action step by step? $\endgroup$ – Ilya Kanatov Oct 12 '15 at 19:44

    $\begingroup$ that is really weird... :/ I don't know how to help. It must be a Mac-blender bug, because it works perfectly on my windows and my linux $\endgroup$ – Scalia Oct 12 '15 at 19:45
