Hi, yes PMC help for indoor render.
Set diffuse/specular depth to 6 or lower, check coherent ratio 0.5 need a few hundred sample to clean but render much faster.
Remove the wall in back of the camera or add a big mesh emitter with low value to get more light in the room.
Such an image should be noise free in 2-3000 samples or something is wrong with material/light setup.
Cheers, mib

Try to increase the samples on light and render settings for specular and diffuse.Matteo3d wrote:Hello guys,

Octane is not 100% unbiased, it uses probabilistic methods for all kernel modes.
