Subject: HDRI chrome balls, how to map?
OK I've got this great job coming up and I'd very much like to render it
using hdri... but having read up on this technique in the documentation I still
have loads of questions... I get the whole imf_copy thing so that's fine and as
long as I'm working with a HDR image that has been unwrapped into a spherical
projection I get very nice renders... so at the risk of sounding like a
complete idiot I'd like to ask how exactly you guys use the HDR images that are
shot from a chrome ball... How do you map them into your environment? How do
you go about unwrapping a chrome ball image to be mapped spherically?
Thanks in advance.
