# Light Probes

Flora supports legacy baked probes and APV-compatible workflows.

## What This Affects

* Indirect lighting accuracy on instances.
* Per-instance memory use when probe data is stored.

***

### Legacy Light Probes

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

1. In [Scene Settings](/scripts/scene-settings.md), `AllowLegacyLightProbes` is enabled.
2. In [Runtime Settings](/scripts/runtime-settings.md), `DisableLegacyLightProbes` is disabled.
3. Prefab renderers use probe sampling (`BlendProbes`).
4. Scene contains baked probe data.

***

### Adaptive Probe Volumes (APV)

Flora is compatible with APV through SRP lighting workflows.

## How To Verify

* Bake probes/APV data.
* Compare instance lighting with probe toggles enabled/disabled.
* Confirm expected memory/performance tradeoff for dense instance sets.
