Trying to use Scriptable Objects that refer to Subscene Objects, Getting "Type Mismatch"

[limber finch]

I have a system that makes a vehicle entity follow a set of waypoints.
Currently, I have an authoring object that accepts a "LoopSO" object, which has a list of float3 waypoints.
The vehicle baker is responsible for loading the waypoints into a dynamic buffer.

Instead of using hardcoded points in the SO, I'd like to refer to GameObjects/Components in the subscene, but I'm getting "Type Mismatch" when I try to include the field. I understand that the "cross-scene" reference is refusing to serialize. But, I don't particularly care about maintaining a reference to the baked entity. I just need the SO reference to the GameObject in the baking scene for the vehicle baker that's loading the waypoints into the buffer.

Anyone have any suggestions for a workaround?

instead of using a SO just store the 'points' (gameobjects) on your authoring script

you can't reference objects in scenes

I was just typing a reply to that. It works, but it's not ideal. Lots of repeated configuration and I wanted to leverage SO's to manage the configuration easily.

well you just can't do it on a SO reference GOs in a scene for a simple reason
what if you load the same scene multiple times, which one is it referencing?

best i think you could do is use float3 but then create custom gizmo handlers

so they appear in the scene and are draggable to make positioning easier etc

Makes sense. Guess it'll do. In my mind, these GOs are more like structs or " value objects" in that I don't care which object the pointer is pointing at, only the data that it contains.

As an aside, @sullen trench, appreciate all your thoughtful and detailed forum posts. It's been an invaluable resource as I've been using ECS over the last 12 months.
