amplify-impostors

What problem does it solve?

Amplify Impostors help you render distant objects (trees, rocks, props) efficiently by baking high-poly geometry into lightweight texture atlases and a small quad mesh, drastically reducing draw calls and memory while preserving visual fidelity.

Core Features & Use Cases

• Bakes atlas-based impostors for Unity URP/HDRP and BiRP pipelines.
• Supports Spherical, Octahedron, and HemiOctahedron impostor types for flexible LODs.
• Integrates with Gaia, PW Tree FBXs, Vegetation Engine, and other vegetation toolchains to replace distant meshes with impostors.
• Produces assets: impostor texture atlases, a generated Mesh, and a runtime Material wired to the baked outputs.
• Handles LOD replacement and optional automatic or manual shape generation.

Quick Start

Open a tree prefab and run the Bake Impostor flow to generate the impostor atlas and LOD.
