SYSTEM DOCUMENTATION & REQUIREMENTS

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.

Frequently Asked Questions about amplify-impostors

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I bake impostor billboards to reduce draw calls for distant trees in Unity?▼

Bake impostor billboards in Unity by converting high-poly geometry into lightweight texture atlases and simplified quad meshes. This process drastically reduces draw calls and memory usage while preserving visual fidelity for distant objects like trees, rocks, and props.

Can I use baked impostors with Unity URP and HDRP pipelines?▼

Baked impostors fully support Unity URP, HDRP, and Built-in render pipelines. The tool generates compatible runtime materials, meshes, and texture atlases tailored to your specific rendering pipeline.

Does baking impostors integrate with Gaia and Vegetation Engine workflows?▼

Baking impostors integrates directly with Gaia, Vegetation Engine, and PW Tree FBX workflows. This allows you to seamlessly replace distant meshes across your vegetation toolchains with generated atlas-based impostors.

What impostor projection types are supported for LOD generation in Unity?▼

Supported impostor types for Unity LOD generation include Spherical, Octahedron, and HemiOctahedron projections. These options provide flexible billboard rendering and mesh generation to match various distant geometry shapes.

How do I generate an impostor LOD for a tree prefab step by step?▼

Generate an impostor LOD by opening a tree prefab and running the Bake Impostor flow. This automatically handles atlas packing, dilation, mesh generation, and outputs the runtime material and texture atlases.
