unable to get rid of flicker and noise

[jim99]

Hi Guys,

I am having issues of getting rid of flicker and noise ( lower left corner in the animation). Maybe I am doing some wrong, I have try turn up all the settings I known of GI clamp is on 1.0 and path tern power is on 0.1....
I might be missing something maybe something to do with light materials?

Cheers

Jimmy

Gif animation to explain the flicker better..

I think you just need more samples to render this scene. I would also try rendering in higher resolution and then scaling it down or do some post noise reduction.

Did you try increasing the sampling rate of your light sources? I believe 1 is not enough.
Also try increasing caustic blur

Cheers!

Yes turn caustic blur to 1. Turn up small lights to 1000 samples and use a denoise plugin in after effects such as neat video. Octane in not good at rendering small lights.

I think there is no reason to set light sampling rate to 1000 in this scenario. Sampling rate controls how much weight is given to the emitter when picking an emitter to sample. If you put all light sources to 1000 then it would be same as it would be dafault at 1. Use sampling rate to balance your lights.

Thank you for this! I tried it out today on some noisy animations and they cleaned up like a dream!! I just bought the pro license

noise especially on dof lights will never go away. this is how octane renders. And static noise does not really work

Thanks guys,

I tried with 50000 sampling rate on each light, and rendered it again. It helps abit but I can still see noises...
also max samples is on 3000 GI clamp 1.0 path term.power .01

I haven't tried caustics blur setting yet, I will try it today

what else I can do ?

Is this the https://www.redgiant.com/products/denoiser-ii-color/ plug you are referring to ?

Thanks

I got a project that requires me to render( animation )something like this ( see image below )

I want to use octane to try it out but do you guys think noise will be a problem in this low light scene ?
or Maybe just give up use vray instead..

looking forward to your advice...
