Vehicles/Tanks
Our tanks have roughly an interior created of 80,000 Triangles, and an exterior of about 10,000 triangles.
Additional information:
We use 4 (for PZ4, T-34 uses 3) texture pages 2048 each. One for each of the following, driver/Hull MG, Turret, Basket/ammo, and a tiled page. For the tiled page we included walls, cylinders (because they do not need to be normal mapped) wires, nuts/bolts, and things with writing on them. Also include on the tiled page things that are not directly in the cameras view. Only bake things that are going to be directly in front of the camera (Like optics for example)
So if the tank interior has 3 main metal colors, make a black tile, green tiles and white wash tile (for the walls) then float the appropriate UVs on the correct tile
