Here's what I am trying to achieve using Newtonian physics.
Emit particles perfectly vertically from a plane.
If I animate the plane, the particles in Newtonian physics will naturally drag behind which I don't want.
I tried baking or caching the particles while the plane was static. So the simulation is locked in the way I like it. But then moving the plane the particles don't follow anymore, and there is no baked particle object I can find to parent or constrain to anything.
Note: This does work with fluids inside a domain. I can bake a fluid simulation in a domain, then animate the domain object (translate, rotate, scale) and the baked simulation follows as expected since it is baked in the domain space. Is there a way to achieve similar behavior with other particle systems ?
