I hope that the unofficial to-do list includes in the near future
something about materials/visuals. Right now we are creating a whole
building in one definition of grasshopper and we have to be baking
constantly to see what we are doing. It would be nice at least to be
able to automatically assign geometry to different layers (with
different materials in them) so we only have to bake once the whole
definition. Right now we are baking each object individually and
assign it to its corresponding layer.
