Caching rendered previews - how does it work?

Corona Corona for 3ds Max General

Can we get some more information about this new functionality listed in Corona 10?

“Significantly speeding up material editor by caching rendered previews. Full material editor is up to 22 times faster.”

When will it generate, where is it saved, is the cache saved so that you can close and open max and not having to generate it again, in what cases did the preview generate when not needed and now saves us time, does it affect the previews of material libraries so these now also are cached between sessions, etc

Any info into the inner workings would be great :smiley:

Hi,

Here is a reply from the devs:
“Anytime 3dsMax wants to render a material review, we check if we already rendered a preview of exactly the same material (with the same settings) and if yes, we return the cache preview. The caching is not persistent between 3ds Max sessions. The 22x speedup comes from the start of editor of a new scene, where it pre-renders 22 previews of the same material.”
