GPU Infinite Grass (Patreon)

"GPU Infinite Grass" is a grass rendering system for VRChat worlds and other projects on Unity Built-in Render Pipeline. It's not just a shader, but a system that uses GPU Instancing to render grass batches in a very performant way. It is designed for VRChat worlds and can be used for both large open environments and small worlds. Can render millions grass instances on PC with no lags.

Main features:

Fast batched instancing rendering

Renders a large amount of grass using GPU instancing

Works on meshes. Unity Terrain is NOT supported!

Supports multiple mesh surfaces at the same time

Supports VRC Light Volumes and Unity lighting

Supports baked Light Volumes (Use it instead of baking Light Maps)

Supports point Light Volumes

Supports Unity realtime lighting and shadows

Paint-based grass placement

Assign surfaces and paint grass distribution directly with a brush

Includes Eraser and Fill tools

Supports up to 3 grass types

Interaction

Grass bends from players and moving objects

Trails and grass bending works infinitely and seamless even in huge worlds

Scales from huge to small worlds

Player-centered rendering area supports large open terrain-like spaces

"Target Override" allows to create static grass zones for easier tuning in small worlds

Optimized for PC and Quest

Performance can be controlled by limiting Draw Amount, distance-based grass simplification and culling

Uses smart culling including camera frustum culling

Suitable for PC and Mobile/Quest workflows

Visual customization

Per-type controls for 3 grass types

Size, width, randomization, wind, trail response, and random grass textures support

Advanced features such as Cloud shadows and Subsurface Scattering

Examples included

Includes an example scene to help with setup and tuning

Includes a prefab that can just be drag and dropped into your scene

How to use (quick)

Drag and drop the Grass Particle Surface Manager prefab into your scene

Assign the meshes you want to paint in the Surfaces list

Paint grass with the Paint tools

Tune look and performance in the grass material/shader settings

Please, test the performance in game! GPU Infinite Grass is very optimized, but not free.

All major parameters include tooltips, so you can read how everything works directly in the inspector.
