Turret hide my body

[Renegade]

[...]writing the art.ini guide was necessary because, although referenced several times in its files, DeeZire's Guide does not include an art.ini guide.[...]

And about the question...I think you don't know what you're doing.
Your turret has to be "closer to the screen" than the tank body, otherwise it'd look like the tank's turret is below its body. If your body is hidden by the turret, then most likely it's either caused by the turret being too big, or the body being too small. Try resizing either component until they form a sensible whole.

If that is not your problem, you should go into more details.
