Hi
have you try without Global illumination ?

In some cases, rendering in interior mode can help.

Before your question can be answered, we need to identify the cause of the noise. If you can attach your scene as a .ksp file, it'll be easier to help. Do you have physical lights in this scene? What are your render settings?

The last attached image is in interior mode with only 6 Ray Bounces, and still there is white noise.

I did so with 64 samples, and the white noise is still there, as you can see.

Do you use any emissive materials or physical lights in your scene?

Will Gibbons

Also, add some subtle roughness to your materials that are showing white spots, and make sure they have a material samples set to about 16. Your render samples should be good enough around 64. Make sure you have global illumination turned on. 10 Ray Bounces should be plenty.

Not close to this noise.
