Pretty major update to the veiny guy scene file - looks better, runs smoother, calculates faster, just generally a lot more Farmfieldish. :D
Scene file: www.bit.ly/ff_shortest_path_RnD
Updating an old scene file share I got sucked into playing around with the shortest path SOP and this is the first of two scene's that I'll share from that - I'll drop the the next one in a day or two where I'll do some fun stuff driving point clouds and POPs with the underlying curves...
