What makes JustGrass different?

It's Performant - Using frustum culling you keep unseen grass from ever reaching the GPU pipeline, so dense fields only render where you look. If you cant see it. Why render it?

AudioLink and VRC Light Volumes Integration - Audio link and VRC Light Volumes just works! It is not a requirement to be in your project but I would definitely use it!

Its Interactive! - Grass responds to more than just wind. There is a player collision system that bends and displaces grass as people walk through it. Complete with a trail effect.

[There's also a separate custom object collision system that lets you displace grass from any object you choose. Vehicles, Thrown props, or whatever your world needs.]

Clean and Fast Inspector - This shader uses LWGUI (install tutorial in the README, its super easy.) This shader GUI makes working with this shader a breeze! Toggle on and off anything you need or don't want.

Its rendered on your GPU! - Each blade of grass is generated procedurally on your gpu from your mesh using tessellation. Its DENSE, capable of splitting a triangle up to 32x!
