Where's my spaceship? {the Newb returns]

I've been getting 3ds objects to appear on my computer screen with my jme code for a couple of weeks now and had mistakenly thought I had how to do that all figured out. So I thought I'd try to make a simple game where the player flies a spaceship around a small defined space from a top down view. I'm using a quad to create a basic star background.

All the code should currently do is create a background and then place a 3ds spaceship above the background. The background works great, but I can't get the spaceship to appear. I commented out the background to see if that was somehow interfering, but all I had then was a black screen. I've tried moving the camera position and the spaceship position to see if I simply have the ship out of the camera's line of sight to no avail. I suspect that the spaceship is not even being rendered and I suspect this is due to me making some newbie error.

I'm hoping that some kind soul will be able to scan through my code and instantly spot my error.

try a box instead of the spaceship:

box is there -> something with model loading is wrong

box is not there -> something with the scene is wrong

Good tip, thanks.

You know what I learned? It's important to define the camera's Frustum. Yep. Sure is.  :stuck_out_tongue:
