Object moving through another

#1

Is there a modifier or armature lay out or some trick to make one mesh move through another deforming it as it moves through. I’m trying to mimic the cartoony hose effect where the hose fills with a large bulge of water and the water moves through to the end.

Yet I can’t seem to figure it out, I want a shrink wrap like effect yet it deforms the hose too much, simple deform moves everything around too much and I would dread the though of rigging an armature system.

Is something like this possible or is it a lost a cause.

You could use a lattice modifier and a deforming lattice moving along the hose.

Do you know of tutorials showing how this was done. I search for several, but none looked anything like your video.

I have been able to get the lattice to deform the oval its parented to but I don’t know to get it to deform the hose. (probably not going about it the right way)

Also would I be able to parent the lattice to a curve so that it will only slide along that curve (and possibly bend with it as well, otherwise I’m not sure how I would use the same deform method on a curve in the hose.)

Thanks again for any help

I’ve attached the blend file I used for this.
A lattice can follow a curve like other objects.

I’ve seen that being done once where the hose was a softbody object.

Why not cast modifier?

I don’t have much experience with the cast modifier, I tried it but it just make the hose stick to the surface of the ovalish object. I’m not sure if there is a way for the hose to maintain it location and basic shape and just deform around the object.

I’ve been playing around with the lattice and got it to do somethings I’d like, though still not very good with it as well.

Richard, did you make that video specifically for this thread? That’s pretty cool of you do to that! :slight_smile:

Like I’ve said, you can do it with softbody too. In fact I’m baking a simulation right now. Only I went a little overboard with the sim, so my old Celeron CPU is churning away on it now. When it’s done I will upload it.

It didn’t come out as good as I hoped it to be, but you get the general idea. I should have make the springs stiffer and use better collision.
