How exactly does one cast a shdow onto an hdri light probe image - since most
are cube or sphere mapped images?
Does one map a non-emmisive copy just inside the emissive one acting as a light
source? Just wondering how to make it reasonably seamless, as the scenes I've
seen so far are on tables or other occluding surfaces.
This just occurred to me:
Can I add a y-gradient to the finish {} block, going from emission 0 to 1?
Thanks!

You just need to make it non-emissive, diffuse only. Next, put it in a
light_group. That way, ANY object can cast shadows onto it. Be sure that
you don't make it to large.

That you can't, but you can put the gradient in the texture block, and
use a texture map going from one texture with emission 0 to a texture
with emission 1.
