heres the code:

guienv.drawAll()
driver.endScene()
Wend
device.drop()thing is, no matter what I change the camera rotation to.. it always points at the mesh, instead of pointing in the same direction as the mesh.
AND
if i put the camera behind the mesh it NEVER faces the ship
EDIT
nevermind I had to bind the cameras rotation and target
