    Theres an api for runtime, and I found a messy workaround to copy a prefab entity's components inside of a baking system but if I want to do some stuff inside of a baker I cant appear to find anything currently that isn't internal to support this. Is this planned in any way?

    Not sure about adding the components itself. The way I've done this so far is to do `GetEntity(gameObject)` on the GameObject that the graphics (Mesh Filter etc) is on, and then spawning that (both inside the baker).

    As far as I can tell, the `GetEntity` does the conversion of the graphics stuff automatically (it converts the components to their Entities Graphics counterparts for you).

    You can just replace the RenderMesh in a BakingSystem, seems working fine for me. To be sure, maybe its good to do it in the
    Code (CSharp):
    1.  
    2. [UpdateInGroup(typeof(TransformBakingSystemGroup))]
    3. ...
    4.             var renderMesh = EntityManager.GetSharedComponentManaged<RenderMesh>(entity);
    5.             renderMesh.mesh = newMesh;
    6.             EntityManager.SetSharedComponentManaged(entity, renderMesh);
    7.
