I was trying to Flat shade a Flak Cannon model and a laser rifle model yesterday using Torque DTS Plus exporter in Milkshape 3D but it would absolutely not work. I tried exporting anything using the damn DTS Plus exporter and it would simply refuse to work (Only one polygon out of the entire model would appear, everything else would remain invisible)
Edit: Problem solved, thanks to MasterLegoDude's Making a weapon thread.
