An extra idea to optimize built scenes when handing data to clients
Strip "Texture(s)", Strip "Mesh(s)", Strip "Mask(s)" Tools commands
All depending on what your selection (Chunks) is in the Workplace Menu.
(Of course decimation could be used for Meshes or re-build textures but this all takes time)
I would also be very powerful to propagate your multi-selection in the Workplace menu to actually work when using Batch Command. i.e what ever you have selected only appears in the Batch Window, ready to process by Selection.
