Particles moving inside an moving object.


As in the title. I have a bottle, which have fluid geometry in. But just as normal geometry (screen in attachments). Inside that “fluid” geometry I have basil seeds which are distributed via particles system. Everything fine.

But I need them to slightly move inside, as they will be in water. Nothing fancy, just to see a little movement, also taking into consideration a bit bottle movement. I’ve tested everything I can. Keyed give something but it’s just too weak.

Is there any possibility to do this?


Ok, something is working with particle instance modifier, but I welcome any other solutions.
