Struct OmitLinkedEntityGroupFromPrefabInstance
The presence of this component instructs EntityManager.Instantiate to not to create the LinkedEntityGroup buffer component for every prefab instance, and the prefab child entities are still created. This component is not kept on the instantiated entities afterwards. This component is completely ignored and treated as a regular tag component when LinkedEntityGroup is not present on the source prefab entity.
Namespace: Unity.Entities
Assembly: Unity.Entities.dll
Syntax
public struct OmitLinkedEntityGroupFromPrefabInstance : IComponentData, IQueryTypeParameterRemarks
The use of this component is likely for performance consideration, because creating buffer components is an expensive process involving heap memory allocations linear to the number of instances being instantiated. Omitting the LinkedEntityGroup could make it difficult to associate the children entities with their prefab roots; in such case components with Entity reference like Unity.Transforms.Parent could be useful.
