[Radiance-general] Illuminating objects with a light probe

[Tarik Rahman]

Hi there

When trying to illuminate objects with a light probe made from an indoor scene
is it best to generate a cubic cross map in HDRShop and then map each of the 6
sides onto the room walls as 'glow' textures? Because as it is a small scene
with small intense sources, when I use genbox, I never know which is the best
size box to illuminate the objects, i.e. get them in the right position as if
w.r.t. the light source.
Is the best option to use mksource? If I need to map my light probe onto a
distant glow source rather than a large box, what should the geometric
description for that distant glow source be? When creating a mask to combine
probe images in HDRShop, since there is no reflection of a camera/camerman in
the probe (it's a simulation picture rendered with Radiance) what other
artefacts is the mask needed for?

Thanks for any help
