I have a subscene loaded with EntitySceneReference that has a baker with some prefabs that get converted. Everything works in Editor but in Build I get this error:

need code and what exactly is null

#

kind zealot need code and what exactly is null

the top line is Unity.Entities.EntityManager.Instantiate so I assume the entity passed to Instantiate is null

#

the code is literally just em.Instantiate(entity);

#

actually nothing works in the loaded subscene except the fact it gets loaded I think (Streamed scene with 35ms latency from /root/GameServer/dark_Data/StreamingAssets/EntityScenes/14e7242b07f58ad488c55cbfa186338a.0.entities)

#

my system doesn't even run

#

again in Editor everything works perfect

#

this is how I bake the Scenes

public struct SceneLoader : IComponentData {
    public EntitySceneReference SceneReference;
}

#if UNITY_EDITOR
public class SceneLoaderAuthoring : MonoBehaviour {
    public UnityEditor.SceneAsset Scene;

    class Baker : Baker<SceneLoaderAuthoring> {
        public override void Bake(SceneLoaderAuthoring authoring) {
            var entity = GetEntity(TransformUsageFlags.None);
            AddComponent(entity, new SceneLoader {
                SceneReference = new EntitySceneReference(authoring.Scene),
            });
        }
    }
}
#endif```

#

and how I load them cs var world = new World(name, WorldFlags.Game); var systemTypes = DefaultWorldInitialization.GetAllSystems(WorldSystemFilterFlags.Default).Where(type => type != typeof(NetworkManager)); DefaultWorldInitialization.AddSystemsToRootLevelSystemGroups(world, systemTypes); ScriptBehaviourUpdateOrder.AppendWorldToCurrentPlayerLoop(world); SceneSystem.LoadSceneAsync(world.Unmanaged, scene);

show failing code

topaz sparrow Dec 19, 2023, 3:14 PM

#

there is no failing code I realized

#

nothing in the loaded scene seems to happen

#

not even any system run

#

like it loads an empty scene or something, not a clue why it all breaks in build
