I'm trying to do just that but I'm getting  PrefabID is 0! assets/bundled/prefabs/autospawn/decor/v2_cliff/rock_cliff_b_3.prefab  error. 

Does anyone know how to spawn such an object ? 

I feel like it won't work like that

Well I'm getting above error when I tried to spawn it as it was and entity:

1. Crate game object using "CreatePrefab" 
2. Add BaseEntity
3. Spawn component

Normally a prefab should be spawned via Instanciate(gameObject) but it does not work as well (nothing is happening, zero errors, zero nothing). 

As for PrefabID is 0!  issue I think it could be connected with networking (maybe it's an ID used to synch between server and client). 

As far as I know, you can only do so via a custom edited map, not via spawning.

Ok, thanks
