I have a problem which I'm sure is pretty easy to solve but I think i am missing a basic concept.
In SOP I have a surface with scattered points. Now I want to group this points (grouping is animated) and import them to a POPnet DOP and apply forces only to the points in this group, and i just want the (scattered) points only once. Whatever I try, particles get spawned every Frame or the group is not updated. How does this kind of thing work?
Here's how I would do it using a SOP geo as a mask field, you only want particles emitted at the first simulation frame. You have to do it this way for anything downstream of the solver, gravity, drag etc. For POP forces you can use the same bounding volume to for grouping like you had in your initial file. I hope that's helpful
Hi, here's another alternative solution. Using mostly attributes via wrangles. Although I had to replace the Gravity DOP with a POP Force DOP to simulate gravity.
