Help How to Shorten or Scale the Length of an Obi Rod

[josemendez]

As a side note, I'm not entirely sure why you need to use rods instead of ropes. Your tentacles seem to be radially symmetric (so torsional effects will be hard to notice, if at all noticeable) and if you're going to procedurally control particle positions (as in the video in this thread), keeping a rest shape doesn't seem useful either as you'll be constantly driving the shape of the tentacles.
