Unable to achieve noise free and high quality render

[da Costa]

I have recently started to use corona renderer for Cinema 4d and I love using it.
I have also attached images for reference. How to make it better? or could help me with the settings which will give me high quality output.
In terms of lighting I've just used just one light, a camera and basic material with normal and albedo and reflection. motion blur is turned on for the scene.
Please help if you can
Thanks,

Are you using volumetric fog here? It's often pretty slow, unless "single bounce" option is enabled for it.
You should use default render settings in Corona. Since this scene uses motion blur, it may make sense to lower GIvsAA from the default 16 to 8 or 4.
See:

Another idea is using denoising.

How long did you render this image? How many passes are rendered? What is your CPU?

Thanks Maru for your reply ...yes I'm using volumetric fog with just a single light and I've rendered at 200 passes but still I get noise... I'm working on 2.9 GHz Intel Core i7

Do you have the "single bounce only" option enabled for your fog? It should be always enabled.
To get rid of noise inside the volumetric effects, you usually need to increase the Light Samples Multiplier. I'd try with 4.
