Hello everyone, i am making some custom weapons again, and this time i wanna make a glide bomb with fins that pop out. i use a method to do opening fins (discussed in one of my other posts), but it only works for hinge-type openings, not for piston-type openings, which is what i want to do. Does anyone know if it is possible to do it? And if so, how to do it? By the way, i do have a basic understanding of funky trees, but not enough to make something like this, if that's how to achieve it.

Thanks to anyone in advance.
