Grain in Render in Shaderlight Sketchup

Hi I have been messing with Shaderlight in sketch up and every time I try to render there is some level of noise in the renderings. I have messed with the exposure, as well as the shadows boxes. I put in skylight portals as well as moved the direction of the sun. I also made sure the glass was not in the same place as the portals. I’m not sure what to do. I have attached pictures of my rendered space. Didn’t render the whole image but you can see there is noise in the picture. Its gotten better but I cant seem to get it to go completely away. Any help would really be appreciated.
