My goal is to create a simple groundplane in UDK (11/2012 version, fresh install) that the user will be able to run around on. My requirements are therefore very basic and I tried to whip something up quickly in the editor. I created a circular (cylinder) plane and applied a material. I added a Blocking Volume, a Lightmass Importance Volume, and a Sky Light. I built everything and get no errors. The map played fine on my system.
I transferred the file to another system with the same version of UDK (also a recent install). When I try to play the map, I plunge to my death. Though I have verified that my player start position is above the ground, I seem to start below the ground looking up at it. What could cause a map that works great on one system have such a positioning issue on another system?
I believe this is a valid question. I'm obviously going to need to systematically test things and I already have tried moving the player start etc. However, I will need to have some idea of what can differ between installs. I'm extremely new to the UDK.
