Context:

You can see below what effect I'm achieving using the warp modifier:

warp

What's essentially being done here is the radius of the warp modifier is keyframed to gradually increase. You can check it in the .blend file:

What's also important to mention is that there's a custom falloff curve used in the warp modifier, and the increase of the radius isn't completely linear/constant either. That is so I can control how much of the mesh is being warped to the destination over time.

Question:

What I'd also like to happen, is for all of the vertices to have a constant speed during the warping process, which is currently not the case. It seems like it starts off at a certain speed, and gradually slows down as the radius increases.

The problem, as far as I can tell, seems to be that as the radius of the warp modifier gets bigger, it's influence on the mesh becomes weaker. But I'm not sure if that's the case.

But what I can tell for sure is that how quickly the radius increases, directly influences how fast the vertices move from A to B. Which is not what I want. I simply want to control how much of the mesh is being warped, not how fast.

Idea I had:

So, I'm not sure if the warp modifier is the best to use in this case, but I'm really not sure what else to use to get this result. One idea I had however, is to take the original mesh, and and scale it proportionally to get an object like so:

warp2

Then I can animate it's location to get a constant speed, and somehow flatten it back out when it "hits" the destination object, but I'm not sure if that's even possible. Plus it would remove a lot of the parameters that I could control, so I don't know.

So, if you know a solution to this, please let me know!

Thanks!

  • $\begingroup$ Maybe instead use Displacement and Vertex Weight Proximity to control the shape see blender.stackexchange.com/questions/153177/… blender.stackexchange.com/questions/165827/… $\endgroup$ – Duarte Farrajota Ramos Mar 17 at 18:47
  • $\begingroup$ Interesting idea, but I'm not exactly sure how to implement it in this specific situation, can you please explain more in depth? $\endgroup$ – Geri Mar 17 at 19:01
  • $\begingroup$ Make the vertex group affect the displacement modifier, than use some circular shaped object to affect the weight of the vertex group. You can scale the circular object up or down to change the influence radius $\endgroup$ – Duarte Farrajota Ramos Mar 17 at 19:24
  • $\begingroup$ Well I'm getting some interaction between the targeted object and the circular object now, but I honestly can't get it work, I've never used this modifier before, and I don't know what I' doing. Could you give it a try on my blend file? To see if it's a viable option at all? As it looks like with this method, the whole warping thing is gone, or I must've missed something. $\endgroup$ – Geri Mar 17 at 20:01
  • $\begingroup$ Yeah, looks like it can be done, though not sure it exactly matches your requirements. i.stack.imgur.com/jeUVW.gif It takes some tweaking with the min and max values for the Vertex Weight Proximity $\endgroup$ – Duarte Farrajota Ramos Mar 17 at 22:25
