how does V2.x handles instances??

In V1.x instances intersecting objects and other instance created a condition that increased rendering time by a lot. (I'm talking about having a benchmark of 300-400 reduced to 30-35 after adding instances).

Is this still a problem with v2.x?

thanks! :mrgreen:

no, not really....

intersecting emitters with geometry, and even instances, doesn't seem to hurt it as much either.
here's what a standard overnight render can produce (on a dual x5355) given the scene has a fair amount of instances.

here's a crop out from it's full res mother at 6k which sat for a weekend on my little setup consisting of (1) 2.6 x5355 and (2) 1.8 e5 something or others...
there's all kinds of shit intersecting in this scene, a lot of which are instances intersecting with emitters. and a lot of those instances have a sssss layer

hope this is helpful, leo :)

This is only thing that I care if I wanted to upgrade... so yes, you have been very helpful

Sorry to be off topic, but I wanted to stop by and say that I like this rendering.
It only looks a bit too flat/desaturated and maybe a bit too lambert in general.
I did this version in PS quickly, I think i reminds me more now of highgloss magazines and the like. Of course it might all be exactly like the client wanted, I know I did the strangest things to renderings. :)

Agreed to Ben. The scene really has an interesting energy but it needs more material work. Very cool! :)
