cycles indirect lighting question / issue
Quick question if anyone knows, I have been working on a basic scene and have been getting some weird lighting effects from the indirect bounces in cycles.
I am blocking out some stones/bricks with separate objects and where I have small gaps between the objects I am getting this bright glow showing up.
Image is lit with a very dim HDR and a single light, the indirect glow from the interior window/door on the right seems normal, but the bright glow between the bricks is much stronger than I would expect.
I realize I can just seal these gaps off and resolve it, or turn down my diffuse bounces. So I'm mostly just curious if I am missing something in my rendering settings that would be causing this or if it's just a side effect of diffuse bouncing getting amplified in these gaps.
