Flora Renderer 6 v6.3.27 (13 Mar 2026) introduces a high-performance instancing system for Unity 6.0, optimized for rendering dense foliage and instanced meshes at scale. Powered by BRG, the system offers full runtime control and seamless editor integration. It leverages Unity’s BatchRendererGroup API, enabling GPU-resident rendering, native culling, and efficient state switching—without requiring custom shaders or materials. Flora reads tree and detail prototype data directly from terrain components using non-GC APIs, streaming instances in and out based on distance with global rendering to avoid redundant draws. Instances can be selected and manipulated directly in the Scene view using Unity’s transform handles. Any prefab with a MeshRenderer or LODGroup can be converted into a Flora instance or tree, and converted back as needed. Full compatibility with Unity’s Mesh LOD system (Unity 6.2+) allows for fast, auto-generated LODs. Instances fade out smoothly based on screen size or density, with support for LODGroup cross-fades in animated, transition, and SpeedTree modes. Per-light and cascade split shadow culling are applied per instance, minimizing overdraw in shadow cascades. Both GPU-based runtime occlusion and Unity’s baked CPU occlusion are supported. Full per-instance motion vector support enables correct TAA, motion blur, and temporal effects on animated or moving instances, with only active instances submitted to the motion vector pass. Unity’s Light Probes and Adaptive Probe Volumes are supported for indirect lighting. Thousands of instances can be stored in lightweight, serialized containers, ideal for static clutter such as rocks, moss, or debris. All instances are managed through a centralized system with stable handles, enabling consistent runtime queries, animation, and control. A scene-wide spatial hash updates every frame, enabling fast culling, runtime modifications, and efficient spatial queries—filterable by prefab, layer, or type. Runtime instance creation and updates are supported via Burst-optimized queries and data structures, working seamlessly with procedural generation and custom terrain systems. The system correctly handles negative scaling transforms and includes a custom tab in Unity’s Rendering Debugger for visualizing draw calls, LODs, occlusion, and more. Samples include over 50,000 runtime-generated animated instances with motion vectors based on Unity’s ECS boid sample, and terrain samples allowing runtime modification of trees—such as animating, disabling, or replacing them with Rigidbody-driven GameObjects. Compatible with Unity 6.0, supports HDRP, URP, and custom SRPs, and requires compute shader support. Platform-specific compatibility is enabled via the BOXOPHOBIC visual engine.
