Hi I'm trying to use three 3d models in my game. I converted the models from .3ds to .fbx format, to make them work with the XNA SDK. My problem is that the three models seems to be pointing in three different orientations. How should I fix this? Should I open 3DSMax and change the orientation? I tried and failed to achieve this. I tried to correct the orientation from my code but It gave me another problem. I included a screen shot. Normally when I load the two ships, the first one is fine and the second one appear upside-down. In this image, I applied a rotation to the second ship to make it appear correctly. I have code to make the ship roll on the side when you go LEFT or RIGHT with the joystick. The problem I'm having, is that when I move the left ship, it works as expected, but the right ship, the transformation seems to be inverted. When I move my joystick left, the ship is moving left (but appears like it's rolling on the right) and when I move right, the ship moves to the right (but the object is rolling on the left) pleasssssssse help!
