ok,

so I'm trying to fight this noise
would like some help please

i rendered a image DL / 19500 samples the image had minimal noise, but DL is not for interiors.

Then i went to PT / 5000 samples as i had gone through the gallery and seen people doing interiors like that so i went ahead.

2.5 hours later

Image

Do i have to set PT to close to 20,000?

This is my FIRST octane render, So excuse me if I'm asking something stupid.

increase importance on the spot lights, use lights not light material

Where do i find light importance?

also can't seem to get lights working, and from what i searched you have to use materials? i might be wrong though but thats what I've searched and found.

the parameter You're looking is in Diffuse material > Blackbody Emission > Sampling Rate - basically You have to make it bigger so engine would calculate samples of this light faster..Just leave environment & other big lights as they are.

I'm using c4d plugin and no lights work unless they are material lights.

Thanks Glimpse always helpful :)

Would i lose any quality going about this route? or should i just bump up sample rate?

Did you try to reduce GI clamp substantially?
