ummm, how was this?? I think it was something like: First u gotta name the p3d the same as an original p3d(should be at the same siza as the addon), put the original p3d in a pbo that u put in ur island folder, then pbo the island folder, put it in ur addon folder, then place the object were u want them, from the island.pbo, then, when ur island is done, put ur addons, into ur island folder and remove the original(remember to use same name on the original p3d and the addon ;D) and pbo ur island, the it should work...I never got it to work thou, but i don't think i've used addon u can put into islands thou ;D
umm, well, if u don't understand a shit of this, i know, i don't understand myself now
the best way is to ask SelectThis ;D he know, and he can explain in 2-3 lines
;D
