Okay then maybe your n-gons wheren't planar? Luckily blender has select similar: normal or coplanar. (Strange thought: I wonder if different flat or smooth face shading influence normal baking.. never came across this.. does you have different face shading?)
Hi, I'm having problems baking normal maps in Blender. I'm not figuring out what is it that I'm doing wrong but I'm baking from selected to active but the resulting normal map has these shading artifacts that resemble low-poly smooth shading (triangular artifacts that coincide with low poly triangulation). I tried applying…
