Hello everyone!
I've run into a problem. I'm trying to make a game and I spawn four objects right now. The first three are fine and spawn on XYZ 0,0,0. When I do dbMakeObjectSphere for the forth one, it still creates it, but it shifts my whole Z-axis by 50 points. So if previously the origin would be 0,0,0 now it becomes 0,0,-50. I use a rectangle box for the floor, so I don't know if that might be fixed with an actual Terrain or a World. Any ideas how to hardcode my axis or a way around this?
