There is just too much ruddy noise!

[Gazbox_Gaming]

I have been messing around with rendering my scene, and I cannot shake the noise, I have set samples to 3000 (Don’t worry. my PC houses a GTX 1080ti) I have added clamping to it, and portals coming through the window. I have implemented an emmisive node to the sun lamp to increase its strengths and I also have an environment map! There just has to be a way. Below is an image rendered with the above settings

Try adding this to your ceiling and reduce the exterior light a bit

reduce light bounce in render setting will help a lot.

play around with render setting u will find a lot

Nice textures though

I decided to use your shader @Capricas_Kirito I think it works.

Thanks for your suggestion
