Hey,
Please bare with me I am new to rendering on keyshot or any software for that matter and my problem might have a silly solution that I am missing. I am trying to take exterior architectural renders of my building and all the materials seems super grainy, I have tried to render as high as I can thinking that might be the problem. If someone can help I would appreciate it !
my light settings are Basic with global illumination turned on.
It is difficult to say. What are your settings in the render dialog?
Haven't played much with the settings there.
Increase the number of samples. It looks like you have nothing but diffuse materials in the scene. This will require a lot more than just 64 samples.
