If you have the mortar in there, you need to compile the map and when you go into Spearhead, load the map and it should be there. In the editor you only see the black box. I'm not sure what your issue is. Can you be more clear?

I've never had a problem with them, getting them lined up with the ground is the hardest part. IF you want to edit the tiki file you need to find the pk3 that has it, I don't remember, and export it, edit the 'gravity' value and repack the pk3. Other than that I need you to explain more.
