World of Teapots sample count, using adaptive sampling ranging from 8 to 64 samples per pixel, it used the entire range.

World of Teapots, using adaptive sampling ranging from 8 to 64 samples per pixel, it used the entire range. Took 2:12:20 to render the 2K image, using 16 bounces for reflections/refractions and 6 threads running at 5.2 Ghz.

Sample count for adaptive sampling ranging from 8 to 64 samples per pixel, it used the entire range.

Adaptive sampling ranging from 8 to 64 samples per pixel, it used the entire range. Looks better.

Adaptive sampling ranging from 4 to 64 samples per pixel, it used the entire range. Looks a bit noisy.

Random sampling with 64 samples per pixel, finally it looks nice.

Random sampling with 16 samples per pixel, looks way better.

Random sampling with 4 samples per pixel, starts to look better.

Random sampling with just 1 sample, looks noisy.
