The Core GameKit syncro spawner backend displays syncro spawners, connected to the wave specs they use. Those wave specs are connected to the prefabs or prefab pools they use.
Load the scene you want to analyse. Click the Show active scene button in the toolbar to generate the graph. The toolbar’s filter options let you see only certain levels or waves.
The backend is part of the Core Gamekit installation, along with the RelationsInspector Demo.
