Stretchable pipe (for export to Unity) I'm trying to create a pipe that will bend and stretch, which I can then export to Unity. Bending I can do, but I have no idea how or if I could stretch. Is it possible? Thanks :)

What I'm aiming for is, in my Unity game, to be able to anchor one of the pipe to the ground, and then, as I drag the other end of the pipe away, it keeps stretching (increasing it's length).

So - Imaging holding a length of string with one end in each hand. In the dull reality we live in, the string wouldn't stretch, but in lovely virtual world, I'd like the string to extend in length as far as you pull it.

I think I have a handle on doing this in Unity, so if it's not simple for a Blender newb, I'll stick with what I know :)
I'm not entirely sure what you want, but you can make a "stretchable pipe" in Blender by using Hooks:


Add a cylinder with a fill type of Nothing
Add hook to one end by pressing CtrlH> Hook to new object:



This will add an empty with a Hook modifier that you can control the hooked vertices with.
Add a hook to the other end.


Now you can manipulate the newly created empties to stretch the "pipe".
