It doesn't look unusually dark to me. Ceilings are often a little bit less illuminated, in real life they are often painted in a lighter color for this reason. One thing that currently doesn't work in Octane is having sunlight coming into the scene through glass. You can set the glass to 100% transparent to let all the sunlight in.

Hi rafaxf
As Roeland says, I don't think that they are so dark.
I guess that what you have posted is a "raw" render...not postporcessed, certainly with a little bit of postproduction they would look lot better.
What kind of kernel did you used? (the r25 seems to be directlight in ambientocclusion mode)
I really like the r49 one

I think what you mean is the shadow toning.
Try to play with the Ambient Occl distance if you want to stick with direct lighting / AO.
Otherwise use Pathtracing or PMC and push up the exposure a bit.

I know well your problem.
Use a mix of diffuse+glossy materials.
It seem that Octane, when you use only glossy materials with high roughness, renders meshes very dark if they aren't oriented parallel to the camera. If the angle with camera is 1-2° about these surfaces will rendered black.
Then you need to decompose the roughness material part with a diffuse material and add a slight glossy component.
We found another Octane issue when we use not well smoothed meshes. You will notice dark edges even if you add a total white diffuse mat. Octane doesn't threat very well the polygon smooth. This problem never happens with other rendering engines (cpu or gpu)
The only way is to add a turbosmooth (in 3ds Max).
Regards

thanks gabrielefx, thats a nice explanation about mixed materials, and will help me to improve my renders, looking for new angles that i was avoing before meanwhile i'm rendering in pathtracing mode, with better results, but it takes a lot of rendering time..... thx again
