[Radiance-general] Lighting from a light probe

[Greg Ward]

Hi Tarik,

You have to make sure your light probe capture is aligned properly, so 
it's a matter of figuring out the right orientation vectors in your 
synthetic scene.  There are also matting issues in the final combine 
stage.  Are you working from Debevec's tutorial, which was published in 
IEEE CG&A?  See also the thread from November on this list under the 
heading "Alpha channel/object matte".  There are some scripts and tips 
in there.

There are a lot of hurdles to jump in getting image-based lighting to 
work.  A lot of it, you're just going to have to figure out on your 
own, I'm afraid.

Good luck!
