[Bf-vfx] IBL Toolkit - looking for feedback, and sharing blender+photo workflow ideas/needs

Thanks will look into that ;)

There is no way to see the background and the edit mesh at the same time.
That way it's really hard to model what is in the background using the
image as reference.

I see three solutions based on changes in Blender code. Let me know your
thoughts :
(1) to have the editable mesh visible in rendered mode even if without
'cycles material'
(2) to have the background optionally visible in modes different than
'RENDERED'
(3) to support equirectangular (lat long) images in the 'view background
images' as a special mode
(only works with camera

[* a workaround I'm considering is to render the background for the camera
and use as Background image. It will work, just not as a nice workflow. The
second *]

Luxrender alone is based on PBRT so I hope it's compatible with cycles
architecture. The latest integrator we are using may not be in the git. I
will talk with Aldo to see what he is using as reference.
