I'm working on a POP simulation for a rainy window and I've set up the simulation so that source particles (in yellow) fall with erratic motion due to a varying POP Wind force and Gravity force, emitting a stream of particles behind them (in green) as they fall using POP replicate. The emitted particles are stopped immediately after emission (using the stopped attribute in a POP wrangle). The issue is that as soon as the POP replicate is activated (at frame 200 in the video), the erratic motion of the source particles is lost and they travel more slowly in straight diagonal lines (as the trails of the emitted particles show). I believe that the POP interact node is causing this as the source particles are being attracted to the stationary emitted particles, slowing them down. But what I don't understand is that the POP interact and replicate are in separate particle streams so the emitted particles shouldn't have any effect on the source particles. I've attached a hip file along with a video illustrating the change in motion when POP Replicate is activated. Any help would be much appreciated as I'm pretty stuck on this!

What I am trying to do is to get a fluid of any kind (pop or flip presumably) to interact with the fluid in a flat fliptank. Seems like it should be easy, but I can't seem to get them to react and mix like fluids (or interact at all actually). More detail: I actually am trying to get a cloud of blood to spread out into a pool under a body that has just fallen in. Perhaps this means I need a different solution than if I was dumping particles into the tank from an emitter outside of it, but I can't even get that to interact, so any advice on this would be most helpful, and I am grateful to anyone who spares even a moment to consider the problem. Much appreciated! PS- I have scoured the internet, including this site, for advice on this, and have come up empty handed.

Hey everyone, do you guys know a way of making flip and vellum cloth interact with each other? So not with Pop fluid but flip.

Sup guys, I'm trying to make a Fluid pushing a FEM sphere. I've found some information about fluid force + some setting on the flip solver but the FEM object just don't move. I'm clearly doing something wrong. Can anyone help understand what's going on? Thank's, Alvaro FLIP FEM.rar

I have three individual components to this briefcase, the body, the handle rings and the handle, the body is a static objects and the other two are RBD packed objects, all concave. I am trying to get the handle to hang from the suitcase naturally but they are falling through each other, there is a slight reaction but i cant get them to completely react to each other. I have attached a zip of the three .obj files and the .hip file if anybody could have a look. Any help would be really appreciated ! Thanks! Assets.zip

Hi guys, so I'm doing a scene where berries falling into a bowl but I use a sphere and a simple cup modeled to visualize then I realized when I use rbd object on the sphere and static object on the cup, the sphere doesn't drop into the cup but instead it drop just before the cup. I've been trying to figure out but I have no idea why it turns out like that. Any clue what happened? testyog.avi
