A high-performance vegetation system and editor allow you to paint plants on any mesh.

Render pipeline compatibility

The Built-in Render Pipeline is Unity’s default render pipeline. It is a general-purpose render pipeline that has limited options for customization. The Universal Render Pipeline (URP) is a Scriptable Render Pipeline that is quick and easy to customize, and lets you create optimized graphics across a wide range of platforms. The High Definition Render Pipeline (HDRP) is a Scriptable Render Pipeline that lets you create cutting-edge, high-fidelity graphics on high-end platforms.

Description

A high-performance vegetation system and editor allow you to paint plants on any mesh,

unlike the official built-in terrain system, which only allows vegetation editing on it.

It utilizes a GPU instance, template transforms, weight maps, height maps, and result RenderTexture architecture,

significantly reducing memory usage and improving loading speed.

It also continuously captures relevant heightmaps during editing for ease of editing.

Technical details

Using an octree to handle page culling.
Using a compute shader to handle instance culling.
Using a matrix texture to store the results of culling, primarily because GLES3 does not support structure buffers in the vertex shader.
Currently supporting a maximum of four types of vegetation.
Supporting three layers of wind animation.
Implementing a root-to-background gradient effect.
