Hi everyone, i have a problem with noise in my simpy interior scene.
Iam quite new in octan rendere, I used to work in blender cycles but I decided to change it to blender octane render plugin to get better and faster effect.
I dont know what to do to reduce this f**king noise. Maybe i have something wrong in my material setting or render setting?
i havent got IES light, only hdri and sun, havent got heavy model, bump is only on the floor and carpet.
And why it get so LONG? much longer than cycles?
I used this script http://render.otoy.com/manuals/Blender/?page_id=66
and some test to channge rend setting

i use nvidia quadro k4000

pleas help me.

Here you can see PT 3000samp 1920x1240 which lasted 3 hours!


Here is PMC 6000samp 1920x1240 which lasted 9h!


Here is Direct Light 4000samp 1920x1240 which lasted 45min


here you can see some of my quick viz in cycles

The K4000 is not a very fast rendering card.
Better go with a GTX.

Study to see effects of coherent ratio, gi_clamp, path termination parameters. Also set caustic blur=1. Try to add some additional light sources or openings on environment. Don't use high specular values. Stay with diffuse material on walls.

Use more lights.Set Filter wise to 1/ I think by default its 1.2

How many max diff and max glossy depth do u usualy use in this type of interior?
thanks a lot guys!
Ill try it in a few hours and upload a results

Since those new settings I mostly reduce GI_Clamp to 5 and dont use caustic blur = 1 anymore. Without caustic blur and less energy due the clamp there are mostly no fireflies. If there are any I can reduce them setting the firefly feature to 0.7 or so

Hi, what do you think about it?

Direct Light Diff
depth:
diff -6
glossy-10
spec-10
2560x1920 2,5h

is cycles actually faster for you?
