Rigging a stretchy arm.

I’m starting rigging on blender but I have some experience on maya and I was looking at a way to create a strechy arm with a IK setup, but for now I cannot find what I’m looking for.

Does anyone know a good way to achieve that or a good tutorial?

Thank you.
Mathias.

The basics for a stretchy IK setup are pretty simple. In the ik constraint panel, enable the stretch checkbox. Then in the bones panel there is an Inverse Kinematics panel, with each bone selected one at a time, set the stretch field to the desired value. For example a value of 1 is fully stretch, .5 would only allow the bone to stretch half way. This way you can tune the stretch to how you’d like, say upper arm stretch .5 and lower arm stretch 1 would allow the upper arm bone to stretch 50% while the lower arm bone would stretch 100%.
