Okay, I was reviewing my code - seeing how I was going to split up the code into the scene graph. I realized that I'm making a small demo not torque. There isn't that much overlap, contentwise, between the various scenes so the scene graph would really be more trouble than its worth. So I'm not going to add the scene-graph to the demo. All I need do is make a decent particle system as thats the effect thats used the most.
