GPU Instancer Pro v0.9.10 is a Unity asset that leverages GPU instancing and Compute Shaders to efficiently manage and render large numbers of objects, such as trees, grass, rocks, and prefabs, by significantly reducing draw calls and improving overall performance. It simplifies the use of indirect GPU instancing without requiring developers to master Compute Shaders or low-level GPU infrastructure. The tool supports Unity terrain details, trees, and prefabs, offering advanced features for optimizing culling, adjusting LOD settings, and customizing rendering parameters.
The solution uses Unity's RenderMeshIndirect method and Compute Shaders for optimal performance. It includes three core modules:
- **Core Module**: Provides essential functions including GPU-based distance, frustum, and occlusion culling; LOD calculation on the GPU with cross-fading support; customizable shadow LOD and culling per prototype; built-in support for multiple cameras; billboard generation; an easy-to-use API for rendering instances via a Matrix4x4 array; statistical insights such as visible LOD and vertex counts; and the ability to batch draw calls from multiple sources.
- **Terrain Module**: Enables efficient rendering of terrain details and trees with features like native support for multiple terrains, unlimited rendering distance, 'Coverage' and 'Instance Count' detail scatter modes, distance-based detail density reduction, terrain detail LOD support, and runtime add/remove functionality. It also allows customizable texture-based terrain detail density.
- **Prefab Module**: Features a Prefab Manager that supports automatic addition and removal of prefab instances, runtime update of transform data in GPU memory, material variation tools with a built-in shader generator, and the ability to batch draw calls using shared prefabs with other Prefab and Tree Managers.
