# 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.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://flora.magneticarcade.com/rendering/light-probes.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
