Initial test here, settings up for review and discussion later (i.e, define production settings): 4addda3

Settings presets are a great idea.

Attached screenshots for

• Draft
• Intermediate
• Production
• Intermediate Denoise

Missing Production Denoise, but it would be best first to get some consensus on what we define as draft, intermediate and production quality settings.

Draft

Intermediate

Production

Intermediate Denoise

Once defined i suppose we would need to add equivalent presets for appleseed-max|blender|studio, gaffer (? @est77 )

Nice!

A few remarks:

• I would always disable caustics by default, in all presets.
• I would set the Max Global Bounces to 8, even in the Production preset.
• I would reduce the number of Global Bounces in the Draft preset, 3 is probably enough.
• I'm not 100% sure that Min Samples = 1 is a reasonable value, will the adaptive tile renderer be able to compute an initial noise estimate? Ping @oktomus.

As for the other settings (number of direct and IBL rays, etc.), I trust your experiments and experience here, you certainly know better than me which settings work best.

@dictoon got it. I'll set the min samples to 4 for the preview mode.
