GPU Infinite Grass

GPU-instanced rendering for very large grass counts on PC

Brush placement workflow with fill, erase, and up to three grass types

Supports VRC Light Volumes, interaction trails, and Quest-focused optimization

Overview

GPU Infinite Grass is a grass rendering system for VRChat worlds and other Unity Built-in Render Pipeline projects. It is built around GPU instancing rather than a simple surface shader, so the workflow scales from compact worlds to large terrain-like spaces.

Main features

Fast batched grass rendering on meshes and Unity Terrain
Paint-based placement with brush, fill, and eraser tools
Support for up to three grass types in the same setup
Player and moving-object interaction with bending trails
Lighting support for VRC Light Volumes, point light volumes, and Unity realtime lighting
Visual controls for size, width, wind, trail response, random textures, cloud shadows, and subsurface scattering

Assign the meshes you want to paint in the Surfaces list.
Paint grass with the built-in Paint tools.
Tune the grass material and shader settings for look and performance.

Workflow notes

The listing highlights that major parameters include tooltips directly in the inspector. The recommended workflow is to tune draw amount, distance simplification, and culling in the target VRChat world itself, because the system is optimized but still has a real rendering cost.
