I'm able to spawn supply signals without problem but after seeing the smokeEffect and smokeEffectPrefab fields in the SupplySignal class. My understanding is that the purple smoke prefab is called "Smoke Signal Full," but there is a green version of it just called "Smoke Signal." Does anyone know how to change it?

SupplySignal ss = GameManager.server.CreateEntity(SupplySignalPrefab, position) as SupplySignal;
if (ss == null) return;

// Looking through disassembly I found the following fields
ss.smokeEffect = ?; 
ss.smokeEffectPrefab = ?;

ss.Spawn();
