    Why not? You mean instead of the opposite? There’s two “common” coordinate systems with opposing Z.

      Well, it causes moving forward to be on the negative Z-axis instead of the positive, which isn’t intuitive.

      Also, when we’re looking at the front of our model in the editor, the positive Z-axis faces away from us and the positive X-axis is on the left. Kinda backwards.

      Maybe there’s something I’m missing, but that’s the point of this thread.

        Not if you think of forward as “towards you.” It comes from Math. X is right, Y is up, and then when doing 3D, Z is out of the page, bc that’s easiest to draw.
