# Light Probes

Accurate light probe sampling per instance for baked lighting.

Flora supports legacy baked probes and Adaptive Probe Volumes (APV).

## Legacy Light Probes

Per-instance legacy probe data is used when all of the following are true:

1. Prefab renderers use probe sampling (`BlendProbes`).
2. The active render pipeline is not using Adaptive Probe Volumes.
3. The loaded scenes contain active legacy baked probe data.

Terrain trees also require `Probes` in **Allowed Tree Features**. `Terrain.bakeLightProbesForTrees` adds tree positions to a bake; runtime sampling still follows the prototype Renderer and LODGroup.

Terrain details do not store legacy probe data because their placements exist only on the GPU.

## Adaptive Probe Volumes

When APV is enabled, Flora uses the SRP's APV path and does not allocate legacy per-instance probe data.
