Features

Flora offers a range of features to help with your Unity projects:

Terrain Support: Efficiently render Unity's terrain details and trees.
Instance Painting: Paint and manage instances on any mesh surface.
Performance Enhancements: Includes dual-phase culling and GPU optimizations.
Modern Indirect Rendering: Supports DX11, DX12, Vulkan, and Metal.

Rendering

Flora's rendering system is designed for efficiency and performance. Key aspects include:

LOD Support: Supports up to 8 LOD levels with cross-fading transitions.
Batching: Optimizes instance rendering by sorting and batching based on render state.
GPU Streaming: Dynamically manages GPU memory, loading and unloading containers based on camera distance.
GPU Occlusion: Uses a Hierarchical-Z implementation for efficient culling.

For more details, see the Rendering and Occlusion pages.

Shaders and Materials

Flora integrates seamlessly with Shader Graph and supports easy shader patching:

Shader Graph Integration: Automatic patching for Shader Graph with the Built-in renderer.
Flora Shader: Non-destructive importing and automatic synchronization with original shaders.

For comprehensive instructions, refer to the Shaders and Materials page.

Tools

Flora provides tools to populate scenes with detailed vegetation and objects:

Instance Context: Use the toolbar to enable the instance context.
Painting: Utilize painting tools for precise instance placement.

More details are available on the Tools page.

Components

Flora includes several components, each with its own documentation page. Here’s a brief overview:

Instanced Mesh Container: Manages instances of a mesh prefab.
Instanced Object Link: Links GameObjects to instances in an InstancedMeshContainer.
Instanced Prototype: Configures settings for how instances of a model prefab are rendered.
Instanced Terrain Foliage: Dynamically loads and unloads terrain instances based on camera distance.
Instancing Camera Settings: Customizes instance rendering settings for specific cameras.
Instancing Scene Settings: Manages global settings for rendering and culling instances.
