"Renderer" in this case is referring to the MeshRenderer or SkinnedMeshRenderer component. Is there any more information in this error when you click it in the console? If there is a stack trace it would be easier to narrow down. Jon Hogins

Sure. Find the HDRenderPipelineAsset in your project - it is probably in your settings folder. With that selected you should be able to find the setting in the inspector. Let us know if you can't find it.

Good feedback! Sorry to hear you spent so much time on this. We'll try to make this more clear.

We have identified an issue that can cause labels to be incorrect and are currently working on a fix. This problem occurs when all of the labeled GameObjects are destroyed and recreated each frame. One workaround for this is to cache your set of objects instead of destroying and recreating them. An example object caching utility can be found here:

Thanks for the info @JonathanHUnity.
That makes sense as I was previously keeping the items instantiated manually in the scene, but that created ghost labels...so moved to not having anything pre-instantiated when this showed up.
I'll try and setup with caching so I can keep going and good luck with the fix work.

Possibly related - I now receive this error on the camera:

I then attempted to modify the shader mode of the camera to forward, but am unable to do so (I have no ability to access the dropdown):

In theory, per the manual, that seems it is the way to change it:

Could I get any advise on how to switch to forward mode? I am using transparent, invisible geometry for my labelling (with HDR/Lit shader).
