(Overlay) Camera Stacking / Clear Depth Via Script

In URP, overlay cameras have a 'Clear Depth' Toggle.
How can this be set via script?

It can be read from UnityEngine.Rendering.Universal.UniversalAdditionalCameraData.clearDepth but not set?!

Thanks!

 

Standard cameras have a clearFlags property on them. Are URP cameras different? Look in their API... it won't be at a global universal level, it will be at a per-camera level if it exists.

 

The is a clear flag but it seems to be unrelated to the clear depth flag :/

 

I think this is a bug. Indeed changing clearFlags won't affect Clear Depth. The way I workarounded this is that I manually created an overlay camera in unity editor, unchecked the Clear Depth field in the inspector, and then saved this object as a prefab. Later then instead of creating a new camera from script using the new operator, I just instantiated this prefab. It is a very dirty solution, but it works.

 

Code (CSharp):

1. private FieldInfo floatingUIFieldInfo;
2.  
3. floatingUIFieldInfo = currentPlayer.Camera.FloatingUICamera.GetUniversalAdditionalCameraData()?.GetType().GetField("m_ClearDepth",
4. BindingFlags.Instance | BindingFlags.NonPublic);
5.  
6. floatingUIFieldInfo.SetValue(currentPlayer.Camera.FloatingUICamera.GetUniversalAdditionalCameraData(), false);
7.
