I am going through and adding the various layers one by one. Rendering the 600 frames currently takes about 3 hours @ HDTV 25% with no AA/Mblur from the command line.
Here was attempt 1 with the bow cannons:
I have another shot ready now with all the weapons firing for the opening shot. Next will be to add other elements to the shots, make tweaks, and then get ready to send to the renderfarm next month for full render in HDTV format with more features added in post to get an entire 3 - 4 minute short ready by December, followed by 1 more per month.
