Hello. I have pure flat highpoly geometry (i checked normals, scale and vertiсes position along certain axys)
Here is highpoly render
Here is also geometry with no SubSurf modifier.
But when i bake normals via xNormal i recieve strangely deformed map.
Here how it looks at normal map.
I do not understand why this thing happen? How prefectly flat geometry become weird and bake as bad normal map?
