| - | Im assuming you either have done all or most of my other tutorials or are experienced in modeling and the o2 interface, because I'm not gonna hold your hand anymore when it comes to texturing, placing vertices where i say they should be. Making buildings is an easy job because it involves mostly basic shapes like cubes and not much more. Its just a manner of placing and scaling them right and adding a proper texture. Not much advanced selection naming for the LODs either since buildings don't move or have much special features. | + | Im assuming you either have done all or most of my other tutorials or are experienced in modeling and the o2 interface, because I'm not gonna hold your hand anymore when it comes to texturing, placing vertices where i say they should be.

| - | Make sure you got that trick of changing the coordinates of vertices using the shift+E box, because its vital for the next steps. Play with it, try changing a box or a cylinders shape without using any scaling functions. Changing the shape of a structure using this method is a much more accurate one than relying on free scaling using the mouse and the CTRL button. And if we are to make our house of parts, me must make sure that all parts are aligned so that the pieces fit when we assemble it. | + | Make sure you got that trick of changing the coordinates of vertices using the shift+E box, because its vital for the next steps.

| But just having the floor as a reference is getting a bit tired now, so we need to copy the 4 wall structure we just made into the 0.000 LOD so that we can get a better reference. Do this now, Simply go to both the wall lods, select all and copy it into the original 0.000 LOD together with the floor.

| - | One problem; you might have spotted that we are missing a proper geometry structure for the rooftop fence. Without it people might fall off easily. The problem is that when geo structures get thinner than .25 meters, people might fall right through it if they are running fast enough (you might have noticed this in ofp, especially on some fences or buildings with thin walls). So that's why we cant just use the thin roof wall structure we made in the 0.00 lod. | + | One problem; you might have spotted that we are missing a proper geometry structure for the rooftop fence.

| To solve it its best to make a structure thicker than the one its supposed to cover. It might be noticed ingame and confuse or irritate the player (all hate invisible walls in games), but i think it will be OK for out simple fence. | To solve it its best to make a structure thicker than the one its supposed to cover.

Also, make sure its not too steep of you will have trouble climbing it. If this ramp is designed for cars and heavy tanks, then you should note that the steeper the ramp is the easier it is to get a puncturing or damage to the vehicle if you are driving a bit too fast. | + | Notice that if we wanted to have a staircase or a ramp up to the roof instead of a ladder, you would just create a slope with a plane for the soldiers to walk on (make sure it is connected to both floor planes or you might get some trouble).

Well, hope you have enjoyed the tutorial and learned the basics of ofp building creation. Still some stuff to learn, but this is the most important parts. Note that for the sake of this tutorials simplicity I skipped making a Fire Geometry LOD, since it was learned way back in Lesson 4. You will notice that without such a LOD you will be able to shoot strait trough the building. You can make a Fire Geo real fast by just duplicating the Geometry LOD and changing the copy to Fire Geo. See lesson 4 for more info on this type of LOD. | + | Yes, we have done it! Our little house is complete, its got a working ladder, windows to shoot out and the AI can navigate it pretty much OK.
