Took about 15 minutes to render. Uniform indirect illumination sampling with 1 sample and 4 bounces, 16-256 primary samples, 4/64 soft shadow samples.

Took about 15 minutes to render. Cos-weighted indirect illumination sampling with 1 sample and 3 bounces, 16-256 primary samples, 4/64 soft shadow samples.

Fixed the averaging thing. Same parameters as before, but took 1 hour 10 minutes this time? Mightve just been because I was working on other stuff while this was running in the background.

Forgot to average the final indirect illumination color--enjoy my unintended sun. 8 indirect lighting samples, 1 bounce allotted each. Took 33 minutes to render.

First attempt. Scene is way too dark for some reason--one indirect illumination sample and one bounce only. Took ~2 minutes to render.
