   Object Disapears After Out of View
  I have created a simple FPS model, and as soon as the character is out of view from the camera, it is impossible to get it back? I wonder if this is a common problem and relates to a rendering problem somewhere?   
  Can't get it back?  As in you move it off the screen, and then move it back on the screen but it never shows up?If so, you have a problem in your positioning math or your culling algorithm (if you're using one).   ;  What you have explained is exactly what happens. I will check out my culling techniques, if this is what you expect it should be. My positioning math just directly calls the Matrix and uses a variable to change it, mView._41 = MoveX;mView._42 = MoveY;mView._43 = MoveZ;However, I just tested it out and I can move the object around (without touching the mouse) and I can send him as far as I want and he'll come back. The second I move the mouse too far, in other words the camera rotates too far (I guess) the guy dissapears.I think it might have something to do with some rotating math, but I'm not too sure.Is this common? The camera rotates to a point, say a full 360 degrees, or past 180 or something and it has reached a limit and just dies? lol   ;  I doubt it's in your positioning or camera, especially if you can still see other things on screen (if not, try placing a number of those objects spaced around you in a circle and see what happens when you rotate.
