Prefab variant inheriting source values with extended script replacing a component.

Is there a way to create a prefab variant and replace a component with an extended version of itself without breaking the connection?

Right now you can delete the original component on the variant and add the extended version (at the bottom since re-ordering components also breaks the prefab link), but it would be nice to have the shared values between the source prefab's inherited component where no deviations designated in the inspector.

 

I just tried changing the 'Script' field (with the inspector in debug mode)
I got a

error.

you can try to avoid inheritance and refactor the 'derived' script to a separate MonoBehaviour with [RequireComponent()]

 

My impression is that this is not possible. I however don't have an overview of the approach of switching the script reference as described by M_R, which logs an error. We'll look into this.
