Get an inside look at how it really works!   Advanced multi-threaded memory management Autograss uses Happy Digital's advanced memory management system. That means Autograss uses only a fixed amount of RAM no matter how much grass is in the scene, whether it's a one-acre lawn or an entire golf course. No crashes, no nonsense. And it's fully multi-threaded, so all your cores are driven to their full potential.   Rendered in 18.2 seconds

Realistic grass presets

Autograss includes eleven preset grass types covering the most commonly used grasses. You don't need to model any grass. The scientists at Happy Digital studied radiometrically calibrated photographs to ensure the grass presets have true-to-life shape and color when used with V-Ray's physical cameras and sun / sky system, from sunrise to sunset. In addition to these presets, Autograss provides you with mapping and variation to produce special effects like worn-out trails and lawnmower paths.

Easy. Fast. Realistic.

Finally you can have it all.

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 works in your scene.

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.

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.
