I know I should keep my emitters to the lowest amount of geo possible, also use IES. But I am trying to light about 12 cabinets, they are like 1 ft by 8 inches. I have small 1 plane IES lights in each cabinet, but I can not for the life of me get it to render clean, no matter if I use PMC, or DL Diff or AO. I also cranked up the sampling rate to 8.0 and still cant. I am rendering with 4 titans, and its 1980 x 1080. The longest I have rendered is for about 30 minutes. Anything else I can try for this? I only modeled a corner of the room for the set, and I have walls all the way around, along with an hdri shooting light into 4 rooms. I have even tried turning off the hdri and deleting all the walls, hoping it will reduce the noise, but I can still say I narrowed it down to the small light sources. Any more ideas I can try? Or is it just going to be a long render time....

Have you tried setting hotpixel removal to 0 and caustic_blur to 1?

I will give this a go in the morning. I am doing an over night render to see if that works, if not I will try your methods and let you know. Thanks!
