I created a Test.zed file, a simple cube just to make sure my building worked (to make sure I dont waste a lotta time modeling a building that becomes that doesnt work). I then converted it to .zvl, then from zvl to .div, next, from .div to .vol. I then registered the vol (registervolumes.cs) started up the editor in F3 I saw my building in list, when I seleceted to create it tribes shut down. Whats wrong? I know Im being a bit vague, whatever extra information you need just ask.
