Light noise at night

[ThomasVINCENT]

Hi,
Since i use KeyShot i didn't get to fix the noise on the render when i use light materials.
This time i ask you if you can help me.
I don't know if the noise come from the light or the material "touched" by the light.
There is a little bit noise on the yellow part of the boat and a lot on the metal structure.

Thank for your help.

Same problem here.

I think the bump surfaces have something to do with this.

But no clue on the solution.

Had this same issue. Using emissive and area lights and a rough material for the ground plane.

Did you try to add a ground in keyshot ?
In my memories it can change the light on the ground.
