My render settings from the D3D Render Firefly dialog.

Notice my IDL values - of course I adjust them for every render, but this one is easy to remember because it's a number joke.

Intensity .66 (ok .65 here but that was a typo)

Bounces 6

Samples 600 (or 666 if you like)

IC 60 (or 66 if you like)

These are really easy to remember - all 6's.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
