Okay, I apologize in advance if this has been covered somewhere else.
I also apologize if this is something very simple that I am unable to grasp or have discovered yet.
My problem is that when I import a 3D model (a spaceship for example), on occasion the model is lined up precisely to the red, blue & green direction arrows. So when I move the ship forward....it goes forward as it's supposed to.
On other occasions those arrows aren't lined up to the model's x,y & z axis....hence when I attempt to move the ship forward, it does so at an angle, with it's nose pointed to the left or right. You know what I mean?
I know this is something obvious.....but can you help me out?
