you could creeate fakebones yourself but its realy hard
i tried my self and there where a few problems

-the movment off bones is a slight differnt(because of the movement of the parent bones)
-you will need ent_clone because you will need vec_to_mesh
-is litle bit heavy
-use more memory
-more lines of script but after all no problem i converted everything to smal functions so createa a bone white parent was 5 lines
then you use it like normal bones
-no (med)editor


great things are
-you can use more vertex for every bone
-creating bones during rune time
-adding vertex during runtime

i never fineshed it but if you want i can give you my script
maby you finshe it
