Same parameters as before but only 2 reflection/refraction bounces. Took 2 minutes 55 seconds to render.

Fixed my soft shadows and implemented glossy reflections/refractions and multiple scattering. This took 8 minutes and 22 seconds to render on my laptop with 20 threads. 5 reflection/refraction bounces maximum. 16-256 primary ray samples per pixel. Either 4 or 64 shadow rays per primary ray. A flat 2 samples per ray for the normal/half vector sampling in glossy reflections/refractions.

Incorrect Soft Shadows Example 1

Render after implementing smooth shadows. This took 22 seconds to render with 20 threads and 16-256 primary ray samples and 5 bounces. Each area light was sampled either 4 or 64 times for soft shadows. ---- The shadows are much bigger than they should be for some reason and are a bit noisy. I havent implemented the glossiness/half vector sampling because I frankly did not grasp it from last lecture.
