Autograss works in any scene, from a cozy back yard to an entire eighteen-hole golf course.
There's no need to divide your scenes into passes or layers.
Yes, you can render the whole thing in one go, and it works with all of V-Ray's great features,
like shadows, reflections, depth of field, and global illumination.
Autograss fits in your RAM.
You tell Autograss how much RAM to use, and it firmly sticks to that amount even in enormous scenes,
thanks to Happy Digital's proprietary memory management system.
The default setting is 256 megabytes.
Of course if you have RAM to spare, you can tell Autograss to use more and get a render speed boost.
And don't worry about setting it too high: Autograss automatically detects when the system is running low on memory and adjusts its own usage to avoid paging to disk.
Rendered in 616 seconds on a 2.8GHz 8-core Mac Pro running Windows XP 64 using high-quality V-Ray settings (min 2, max 24 image sampler subdivs, 0.005 noise threshold, motion blur enabled). The lawn is 30 meters wide and 30 meters long with about 30 million grass blades.
Autograss scales to multiple CPU cores.
Autograss maxes out every available CPU core when rendering.
For typical scenes like the house with lawn shown here, eight CPU cores render up to 7 times faster than a single CPU core.
The speed-up varies for extremely large scenes, but is still several times faster than a single CPU core.
The engineers at Happy Digital put a lot of effort into this feature so that your prized render farm CPUs don't go to waste.
