Tree proxies GREATLY slowing render time...

[StevieBoy85]

Hi, all!

 

 

 

I’m animating a scene in 3ds max 2010 with a lot of trees in the background. I’m using forest pack with proxies of xfrog trees. And Vray 1.5 as my renderer. The scene needs to look as realistic as possible but unfortunately, even though they are proxies, the trees are killing my render time.

 

 

Does anyone know of a good way that I might be able enhance render time but keep the quality? Maybe another solution to placing trees without using forest pack/proxies?

Proxies aren't supposed to speed things up, they're a way to allow you to render large scenes with less RAM.

Of course, there's always ways to speed things up, regardless them being or not proxies. You can kill opacity leaves (VRay is not too keen about them), you can create far trees in post... The same things you would do to a regular geometry.

I earned time rendering using vrmash. Try to use mesh export for important trees and put png files in background in post production (photoshop). I've been working in landscape design field and trees were, and are my big problem..

Your dynamic memory settings in VRay system probably need adjustment. If memory limit is set too low then you are loading and unloading too often to keep the proxies within that limit, too high and you will not have room for the rest of your scene including textures in RAM and you will end up paging to your system drive which is in most cases much slower than RAM. I usually have mine set to anywhere from 25% to 50% of the total RAM in the system. Trial and error will help you find the optimal setting for your scene/system.
