When to use Conformal vs Angle Based when UV unwrapping? When should you use the conformal method verses the defualt angle based method when UV unwrapping? What difference do they make?
Angle Based unwrapping gives a good 2d representation of a mesh while Conformal usually gives a less accurate UV mapping than Angle Based, but works better for simpler objects. (src)
From experience I use a mixture of both depending on how complicated the mesh is, Angle Based tends to give better results in general.
