Scatter on Melting Surface without flickering

Recommended Posts

Hello - is it possible to scatter points on a surface from a melting object without jumping points? 

What would be the best solution for this?

Thanks

Freeze a frame (Timeshift orTimeblend node), have a look at the attribute interpolate and in the scatter "output attributes" check "sourceprim" "sourceprimv" if you look around you'll find examples of this, Im not in the computer right now. But hose are the steps, depending what you want you can have a look at "point deform"

You mean the last file from this topic ?

I tried this, but this does not work with an changing topology.

The problem is the changing topology, your primnum attribute is going to change so attribute interpolate will not yield the desired result. If you use a point deform on a timeshifted mesh you can take the movement from the simulation points and apply it to that mesh. You can then do the scatter/interpolate step in this topologically consistent mesh. I can't upload a file right now but here's what you can do. 

timeshift after dopimport1. particlefluidsurface after timeshift. Drop down a pointdeform. wire the pointdeform inputs like this. 1 particlefluidsurface, 2 timeshift, 3 dopimport. Then do the timeshift/scatter/attribute interpolate process.
