1-Click Impostor Creator!

Optimize your projects with ease by using next-generation Billboard Impostors.

What are Impostors?

Impostors are camera facing quads, or simple polygonal shapes, that replace complex geometry by rendering a fake 3D representation of the original object.

Flexible

Impostors can be moved, rotated, scaled, receive and cast shadows, intersect other objects or impostors, and can be used with LODGroup or any third-party LOD system.

Modern

Making full use of GPU-based instancing, our tool provides Spherical and Octahedron Impostor techniques, the latter being capable of performing smart transitions between different views.

Features

• 1-Click Bake!

• Octahedron and Spherical Impostors

• Billboard Shape Editor

• Smart Blending between views

• Hardware Instancing

• Depth-write for Object Intersections

• Forward and Deferred rendering

• LWRP and HDRP support (v4.9.0+)

• URP support (v7.1.0+)

• Full Lighting and Shadowing (* Lightmaps Excluded *)

• Dithered LOD Cross-Fade

• LODGroup compatible

• Custom Material Baking

Upcoming Features

• Dynamic Impostors

• Batch Processing

Technical Considerations

Currently, standard baking is only supported if the shader exposes a Deferred path, such as Unity Standard shaders. However, the Impostors created can be used in both Forward and Deferred modes. Baking objects with custom shaders is supported via Custom Material Baking

Lightmapping of impostors is not recommended, experimental uses are possible using Amplify Shader Editor; please examine our docs for details:Official Wiki

Please check our Roadmap for more information on upcoming features. This tool is currently in development, performance and quality will be gradually improved in upcoming releases.

* Oculus Quest, and other Mobile-based VR devices are not officially supported.

* HDRP Translucent objects may not bake correctly, known issue in progress.
