No problem
the systems are not hardpointed, they are shown in the ui only, by modifing the .gf txt document that is released with every model, the only other dummy objects you would see are the progressive damage "a1,a2,a3" "b1,b2,b3" always in groups of three moving up the alphabet in a clockwise direction around the ship, and also the pivot points for the .brk model "object01pivot" these will be placed on the axis of each segment you want the ship to break off. and that piece will pivot on your pivot point.
I have two things you require.. 1. the taldren modelling manual for sfciii which explains everything.
2. dderidex ui hardpoint layout editor..
in the modelling manual it explains an awkward way of doing the ui.. later on the editor was released abd makes things allot easier.
download an sfciii model and browse the model folder.. cut and paste the .gf file to your model folder that your building, and name it accordingly (i.e the folder name must match the .gf and the .mod must be named the same- explained in the manual)
then after you have created the vl,ti and bs images and have them in the folder, open up the dderidex editor, when in there open up the.gf and it will show you harpoints layout, of systems and weapons.. (they will be positioned off the model you took the .gf so just move and add yours to where you have them. then save.
just ask if u have any more questions or if anything is not clear.
everything you need is still hosted here
