If you mean things like HDR light probes, then the official version
doesn't output them, but MegaPOV 1.1 does. The HDR images created by
MegaPOV are in the format that's used for mapping back onto a sphere
with "map_type 1", If you want a different format, then you'll need to
convert them with something like HDRShop.
