In V-ray you can set the environment mapping to either angular, cubic, spherical or mirrorball. The cubic is fine, but I don't quite get the difference between the rest.
I got a set of HDRI skies from Dosch and they include Light Probe, where the map looks like a circle, (with a blurred version), and then a Spherical Map.

I initially thought that the Spherical mapping would be used for the Light probe texture, but should it instead be Angular? What map should I use to what kind of mapping?
