This pack is really awesome. Very well done material, and still very warcraftish. I expect great maps/campaigns/cinematics done with it. And approved.
I have a suggestion though. The WC3 model units are the same WC3 in-game units. (The barrel is 64 units big in diameter) If you make the floor sections a 64x64 square, they will fit with pathing map textures in default scale. And they will be very easy to place making ends meet.
