# Render Settings

Attach this component to a [Volume](https://docs.unity3d.com/6000.1/Documentation/Manual/urp/Volumes.html) to override [scene-level](/scripts/scene-settings.md) culling and rendering parameters for Flora instances.

These overrides apply only within the volume’s bounds and can be blended like other volume-based settings.

Distance caps are composed using the smallest active non-zero value across scene/volume/template/terrain sources.

***

### Properties

#### <mark style="color:yellow;">MinScreenSizeMode</mark>

* Controls which objects `MinScreenSize` affects.
  * `Disabled` = minimum screen-size culling is disabled.
  * `RenderersOnly` = applies to renderer templates, but not LODGroups.
  * `RenderersAndLODGroups` = applies to renderer and LODGroup templates.

***

#### <mark style="color:yellow;">MinScreenSize</mark>

* The **minimum screen-space coverage** an instance must occupy to be rendered.
  * Instances smaller than this threshold are culled.
  * Useful for avoiding rendering of tiny or far-away instances.

***

#### <mark style="color:yellow;">MaxRenderDistance</mark>

* The maximum world-space distance from the camera at which instances will be rendered.
  * `0` = This cap is disabled.
  * Non-zero = Instances beyond this range are culled

***

#### <mark style="color:yellow;">MinShadowLOD</mark>

* The **minimum LOD index** used when rendering shadows for Flora instances.
  * `0` = Full detail (LOD0)
  * Higher values reduce shadow quality for distant or low-priority objects

***

#### <mark style="color:yellow;">MaxShadowDistance</mark>

* The maximum distance at which **shadows are drawn** for Flora instances.
  * `0` = This cap is disabled.
  * Non-zero = Additional shadow distance cap

***

#### <mark style="color:yellow;">CrossFadeDuration</mark>

* The duration of **LOD cross-fade transitions** (in seconds).
  * Affects LODGroups with animated cross-fading enabled
  * `0` = Instant LOD switch
  * Higher values result in smoother visual transitions between LOD levels

***

#### <mark style="color:yellow;">RandomizeLODTransition</mark>

* Adds per-instance variation to LOD transition thresholds.
  * `0` = no randomization.
  * Higher values reduce visible synchronized LOD popping across repeated instances.

***

#### <mark style="color:yellow;">MinScreenSizeAffectsLODGroups</mark> *(Obsolete)*

* Migrated to `MinScreenSizeMode`.
* Existing enabled overrides become `RenderersAndLODGroups`.
* Kept for older serialized assets only.

***

### Runtime Override Note

When setting values at runtime, use `VolumeParameter.Override(...)` so the override state is enabled:

```csharp
var sceneSettings = FloraSceneSettings.GetOrCreate();
var render = sceneSettings.GetGlobalRenderSettings();
render.MaxRenderDistance.Override(120f);
render.MaxShadowDistance.Override(80f);
```
