Points follow points

[mapra 3]

Hello everybody!

I would like to simulate particles on top of pre-animated / pre-simulated (cached) points.

So far I only managed to do the "transfer v attribute inside a sop solver" trick. Unfortunately it does not give me the result I imagine.

Instead of inheriting only the velocity I would rather like the points to be attracted by the pre-animated points so they tumble around and follow them the animated ones. 

Basically I am trying to animate some points and then do a simulation on top of it to give it a more natural feel and to be able to art direct the simulation better.

 

I would greatly appreciate if somebody could give me a hint or a solution on how to do that?  

Thank you! 

 

Here is my current progress (particles inherit v):

I was tinkering around a bit more but it still does not look satisfying.

It would be great to be able to control the amount of how much the particles inherit the position of the pre-animated points.

Why you didn't use Pop Attract node?
It has potential for tweak.
