I’m attempting to render an architectural scene with indirect lighting. The scene shown in the attached photo is lit by two linear lights, one of which is behind the camera, the other of which is above the protrusion at the top left of the scene. Both are prevented by surface elements from casting light directly on any of the surfaces shown.
The problem I’m having is probably obvious from the photo: the little points of light on the floor and wall on the right. I wonder if anyone has any tips for making these surfaces render more smoothly?
(bonus points for any pointers on reducing splotchiness on wall directly ahead of the camera–in other renders I’ve typically fixed this by bumping up the QMC sampler rate but that doesn’t seem to be doing the trick in this case…)
