⚠ Requirements

The latest version of the Vegetation Engine is required for the module to work!

The latest version of Amplify Impostors is required for the impostors baking!

The Vegetation Engine is a set of high-quality shaders and tools designed to unify 3rd party vegetation under the same system. Enable high-quality wind motion, interaction, seasons, wetness, subsurface, height-based blending, etc. for all vegetation assets with Standard, Universal, or HD Render Pipeline!

Amplify Impostors is a modern and flexible impostors authoring tool used to bake high-density geometry to quads while keeping the original shading! Impostors can be moved, rotated, scaled, receive and cast shadows, intersect other objects or impostors, and can be used with LODGroup or any LOD system.

○ Overview

Combine the power of the award-winning shading and unification tools provided by the Vegetation Engine with the power of the optimized impostors provided by Amplify Impostors! The Amplify Impostors Module includes presets and runtime shaders for perfect baking with Standard, Universal, and HD pipelines, while the seasons, overlay, wetness, wind, and interaction remain dynamic!

○ Limitations

🞫 Shader Model 4.5+ capable devices are required (Desktop / High-End Mobile)

🞫 Oculus Quest and other Mobile-based VR devices are not supported

🞫 URP 12 Depth Primming cannot be used with impostors (URP 14 is supported)

🞫 HDRP with TAA causes blurry results with impostors

🞫 Lightmap baking with impostors is not supported and is out of scope!

○ Disclaimers

⚑ Due to their nature, impostors are designed to be used as distance LODs. While the baking will match the original shader settings, the lighting will not match perfectly, but it will be quite close to the original!
