So, I create a simple room with window and cast sunlight through the window.
Shouldn't the sunlight illuminated the interior of the room, or I'm doing something wrong? (allthough I doubt cause it's realy straightforward)

Enabled Path tracing?

Don't forget that at this point sun can't penetrate trough glass, maybe for beta3, mean time delete the glass from windows, and should work fine.

Strange for a soft that pretends to be unbiased, and thus totally accurate to reality no?

this is a beta release and i've stated that this feature in not finished.

Radiance

The sun comes in my room. I know about that glass+sun are not working now and since it's beta I dont have a problem.
What I mean, is that while the sunrays come in the room, it doesn't seem like the light bounce off to illuminate the interior of the room.
By cranking up the exposure though, I see that it starts getting some light. But then there are 2 issues:
One is that the white points are blown out and Two is that the render is very noisy.

hi, yeah this is because sunlight is very directional (eg non diffuse like an environment map).

MLT will importance sample this and remove the fireflies and make the render converge much quicker (eg less noise).
so await our next release for MLT.

Radiance

OK. Thanks for clarifying that. I still havent understand what MLT is exactly and its benefits overall, but I've seen some post here and there. You seem very confident in it and so I will be too.
Going back to "play" with what's allready there
