SHOULD READ: Flexi Prims for
Basically using flexi prims for adding non-collidable parts to a build. Stuff along the lines of a large build that has secret passages but only comes in a few parts instead of dozens of tiny stuff like doors that the user needs to place themselves. Basically with 10 drag and 10 tension you get only a tiny bit of twitchiness/movement.
Basically I'm more curious along the lines for things like vehicles and physics stuff. Right now I've figured out that the flexi can't be the primary prim and that it still adds weight to the build. But I just have this itching feeling that there's some other weird rule here and there.
I was thinking along the lines of using it for larger vehicles and using it to make parts flexi if it gets stuck.
