Quote - If you're using my EnvSphere and IDL is enabled, IBL does nothing at all. When IDL is enabled, IBL is like an infinite size EnvSphere. Since the actual EnvSphere you're using is not infinite, it is closer than the virtual one associated with IBL.

If you disable IDL, then IBL will change modes and illuminate everything, even things inside a box or sphere.

Ah, cool - I see now. I wondered about that... thanks for illuminating me :-)

So using that IDL setting with your BB envsphere, should I therefore get the same result with just having the spot and the point light in that scene... without those IBLs being added at all?

Am I understanding that much correctly?
