multi-entity-baker

To bake one authoring GameObject into multiple ECS runtime entities, use the CreateAdditionalEntity method inside a Baker to generate N entities and initialize each with per-entity components like LocalTransform.

To keep baking staging entities out of the runtime world in Unity DOTS, tag your container or staging entities with the BakingOnlyEntity component during the baking process to exclude them from the final runtime world.

To pass additional baked entities to downstream baking systems, use AddBuffer<T> with an IBufferElementData marked as a [BakingType] to store and expose the created additional entities for subsequent baking stages.

Yes, you can generate a procedural grid of tile entities at bake time in Unity ECS by using a multi-entity Baker to create one additional entity per grid cell, each initialized with its own specific component data.

The best way to batch component adds when creating multiple entities in a Baker is to use ComponentTypeSet, which efficiently groups and applies multiple component types to newly created additional entities during the baking process.
