My D&D group gets spends a lot of time in the woods, and every time we do everyone runs around like we are in a field. Well that's not the case now we got TREES! and LOGS!
I dislike tall terrain obscuring game play, that is why the "Trees" are actually stumps and why my forest looks like the Venture Trading Company has come through.
All these models where printed at .2mm layer height, 15% infill, and 40 print speed (mm/s) on a Printrbot Simple Metal
