    marchermitte I did not really understand what your node setup was doing. Attached is a scene that may be along the lines of what you want. It has tentacles that reach towards a null. As the null moves the following tentacles lag behind using the Follower motion modifier. This scene uses scaling to get the tentacles to reach towards the null instead of morphs.

    Thank you Lertola.
    The use of a double null with follower is pretty smart. While this is not what I had in mind (getting the info of the null motion to fire the corresponding morph, ex: morph map "tentacles.bend_Left" when the morph goes to the left, "tentacles.bend_Right" when It goes to the right, etc.). It could work for what I had in mind. I did get more or less the result that I was looking for with polychains and dynamics but It's more like a challenge now to get that direction info translated into nodes.
    Your node setup is impressive for me as I'm not a serious node user.
    Thank you for your time and for the scene that I'm studying more carefully now.

    marchermitte, that looks great!

    Any chance to see how you did this?

    I'm in a situation where I need a tyre shape to inflate in areas until it is completely inflated. I thought about driving a morph with a null, but I guess I need a second null to inflate only the portions I want to "blow up"? In effect, this isn't for a tyre really, I want to simulate a weld being made, it's just in a ring.

    Thanks for any ideas.

    So you want to grow a welding bead in a circle?

    Hmm. My first thought is not to use a morph, but to make a section of weld fillet, (to whatever size /scale is appropriate for your animation), clone it into a suitable size circular array, then use DP kit Part Move to move them in turn from a hidden position under cover of the welding arc.

    Funnily enough, that's what I did, but with instancing and the client doesn't like that he can see the lines of the separated parts. So I wanted to use the morph idea to make the geometry intact so that smoothing would work across it. I just wanted to have a more organic look to it, but even if the morph could proceed around the circle, rather than being all at once, that would be good.

    Here is an example a morph being animated with nulls. Maybe something like this could work:

    You could use a morph along bones and add textured displacement to the bones ( or just a few )
    and as the morph grows it bumps ( and lumps ) as the circle is created.

    Hope it helps
