Crikey, didn't expect to see this bumped today. Thanks very much, kborak.

I have a finished pic of the Landram in action in my gallery. Might as well put it in here too I suppose.
Uni work's got in the way of this now so I haven't been able to texture them properly or follow up on the tank track tutorials I found. It looks like making tank tracks animated in C4D involves Mocha coding which scares the crap outta me.
