Smoothening positions for flat, non-smoothened, triangles is unnecessary and caused positions to move outside their triangle which caused side-effects as rays from those positions intersected with triangles which could not be reached from the original triangle. This is solved by skipping smoothening of positions for flat triangles. A triangle is determined to be flas as its vertex normals are equal.
