I'm hyper aware this has been asked a number of times, but I cannot for the life of me get this of this grain in my interior shots.
Exterior with sunlight is completely crisp, but with the interiors I've:
- Emissive sampling rates 15,000
- Max samples 6,000
- GI clamp 10
- Using Pathtracing, but Direct and PMC are just as bad (or worse)
- currently just 2 long cubes with a blackbody white emissive material on both
- tried adding more lights
- tried adding less lights
- tried adaptive sampling with threshold 0.03 and min samples 256
- tried howling at the moon
Reference image I'm trying to mimic is here:

Closest I'm able to get (after 6 hours of fiddling) is here:

I know we're all sick of these posts, but is there anything we can think of that I haven't tried? I've attempted every comment mentioned in every other thread, and it's still a grainy mess. Nowhere near the sharpness of the reference image.
Someone please lend me a hand here?
