BatchRendererGroup

BatchRendererGroup (BRG) is an API for high-performance custom rendering in projects that use a Scriptable Render Pipeline (SRP) and the SRP Batcher.

BRG is the perfect tool to:

Render DOTS Entities. For example, Unity’s Hybrid Renderer uses BRG to do this.
Render a large number of environment objects where using individual GameObjectsThe fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. A GameObject’s functionality is defined by the Components attached to it. More info
See in Glossary would be too resource-intensive. For example, procedurally-placed plants or rocks.
Render custom terrainThe landscape in your scene. A Terrain GameObject adds a large flat plane to your scene and you can use the Terrain’s Inspector window to create a detailed landscape. More info
See in Glossary patches. You can use different meshes or materials to display different levels of detail.

The following table lists and describes the topics in this section of the documentation.
