Hi there! What is it you need it to do? If you just need it to get in-game so you can place it with the editor, I can help you with that :-) Edit: I've made a .p3d for you, with the different LOD's for geometry, physix, shadows and memory. I dont know why, but I cant get collision with persons working, but collision with bullets or vehicles work. I had to import it to blender for me to use the .obj, files are in the rar you can find here:

I included the mod-folder I used when I checked it working ingame.
Hope that helps
