[Ondra_1]

this is great, but some of the titles need to be more informative - for example: “Speckles/Fireflies when motion blur is on” instead of “Motion Blur”: Motion Blur - Corona for 3ds Max :: Help Required - Chaos Forum

[romullus]

Thank you. Well, i didn’t change titles (yet?), as gathering and sorting all material is big enough work on its own. I’ve managed to index about 1/6th of board to this point. Still much work ahead.

Hopefully with the help of fellow users of this forum, we’ll manage to change titles to be more informative, once this topic will go public.

you’re the man, romullus! thanks!

[Benny_1]

Yes, this has been extremely useful, more so for me than the documentation.
