As on schedule, the coral has been assembled, staged and animated. I might look into rigging and perhaps a controls for animation purposes but at present this is the construction so far. There was talk of including a gradient on concept art and there may need to be a little of colour modification for the final model, the core animation however does appear solid.
In terms of geometry this is not too complex a model when a single instance is around 1.8MB of data. That may multiply considerably when there are lots of these but as mentioned in an earlier post but work was put into minimising the geometry so that lots of these could be on screen at once.
