Thanks for the tips on the periscope stuff! Another question

: is there a way of forcing the game engine to inport the 3ds max smooting instead of performing its own? When I import the model into the game I get weird illumination on some faces (especially those very angled).
EDIT:
Never mind, i've found the answer. In case someone has this problem, here is what I've done. I have selected the faces with ptoblems (those close to very angled edges) and detached them as elements. That was it. Now the smoothing runs ... smooth.
