Is it possible to get a force field to effect a keyed particle system? If so how?
I don’t think you can do that, but what you could try is to make an intermediate shape, say a sphere with a animated displace modifier and then have the keyed particles pass through that animated displace mesh before reaching their final target mesh shape.
Thanks atom, that’s not a bad idea I might experiment with particles with a curve guide also. Actually, do you know if particles with a curve guide will work with a keyed particle system?
