Built upon the foundation of GPU instancing technology, GPU Instancer Pro empowers users to efficiently manage and render large quantities of objects, significantly reducing draw calls and optimizing performance.

Features

GPU Instancer Pro allows developers to easily integrate and manage large numbers of objects, like trees, grass, rocks, or other prefabs, with minimal performance impact. It supports Unity terrain details, trees, and prefabs, providing advanced features for optimizing culling, adjusting LOD settings, and customizing rendering parameters. For optimal performance, GPU Instancer Pro utilizes Indirect GPU Instancing using Unity's RenderMeshIndirect method and Compute Shaders.

GPU Instancer Pro includes several modules designed to improve rendering efficiency and streamline the workflow:

Core Module

This foundational module includes essential functions such as rendering, culling, LOD management, billboard creation, and debugging tools. Although it doesn't have a Manager class, developers can use GPU Instancer Pro's rendering system through the API to create custom renderers. Features include:

• GPU-based Distance, Frustum, and Occlusion culling.
• LOD calculation performed on the GPU and Cross-fading support.
• Customizable shadow LOD and culling settings for each prototype.
• Built-in support for multiple cameras.
• Billboard generation capability.
• Easy to use API methods for rendering instances with a Matrix4x4 array.
• Statistical insights such as visible LOD and vertex counts.
• Ability to batch draw calls from multiple sources.

Terrain Module

The Terrain Module includes tools to render terrain details and trees with GPU Instancer Pro. It features the Detail Manager and Tree Manager, providing the following capabilities:

• Native support for multiple terrains with minimal draw calls.
• Unlimited rendering distance for details and trees.
• Support for 'Coverage' and 'Instance Count' Detail Scatter Mode options.
• Distance-based Detail Density Reduction capability.
• Terrain details LOD support.
• Performant add/remove functionality at runtime for terrain details and trees.
• Customizable texture based terrain detail density.

Prefab Module

Equipped with the Prefab Manager, this module provides an intuitive interface for rendering and managing numerous prefab instances in scenes. Key features include:

• Automatic addition and removal of prefab instances.
• Automatic runtime update of transform data.
• Material variation tools with built-in shader generator.
• Ability to batch draw calls with other Prefab and Tree Managers using the same prefabs.

Minimum Requirements

GPU Instancer Pro supports Unity 2022.3 or higher LTS versions.

The target devices should support GPU instancing and Compute Shaders.
