You do want to go ahead and model your game characters with quads. A quad is just two triangles put together. (If you are using 3ds Max, go to Edge mode and click TURN in your modify parameters. You’ll see.) Modeling in quads just makes your life a lot easier. When you export your model to a game engine it reads your model as polygons=traingles.
Also when you show your model wireframe you should change your Statistics from polygons to traingles. Statistics is under viewport configurations. Again if you are using 3ds Max.









Superb work.
