First step was to make a simple model (above). Then, each face had to be individually mapped, using planar mapping with "best plane" selected; and projection width & height set to 10
Unfortunately, this just produced 329 separate faces that needed to be joined into a net that could be build, and that was a process of trial and error - the first attempt turned out to be unbuildable.
|2nd attempt at a net (this one turned out to be buildable)|
I attempted to make a sturdier version out of plasticard, but 2mm polystyrene sheet proved a bit too thick.
