Windows 10 64 bit, GTX 1080Ti and GTX 660Ti
Broken: (2.79b )
Short description of error
Flat areas with thin triangles often look warped when unwrapped using the angle based method, even though the problematic edges have no angle.
Exact steps for others to reproduce the error
- Create a mesh with multiple long, thin triangles that are completely flat (common case is triangulating a concave n-gon with rounded corners)
- Place seams all around the flat area
- Unwrap using the angle based method
