i finally made my 3d asteroid
i now know how to do it
so first you use blender
i dont know if you can import. 3ds into it but anyhow either you build your 3d model or you import it. in both cases at the end if you see your 3d model
1. save it
2 export it as a direct x file. save it into the media folder
3 put it in the appearnce xml
4 make a new system in xml
5 make it like you would normally.
6 change the name from :planet to the new model entry from the appearence xml:
7 open us2
8 keep in mind you have to save you system as xml and not ubox
open it in us2 and there
your misshapen asteroid will replace a sphere that you previously had.
ill post pictures of my asteroid once im done.
hope it helps!
