hello.
i have an animal that i want to duplicate like a flock. then the flock starts moving on a plane and stops in front of a door. the door opens and they (about 30) goes through the door-opening. thats it…
i have looked at particle emitters such as boids and newtonians but it seems to go nuts. i cant control the movement of the flock.
Blender people is dead, unless you want to revive it.
The only approach I can think of, using particles, would be the harmonic field. You can transfer particles from one mesh shape to another in a flocking like effect. But constraining them to a ground plane becomes the task.
Here is an example file of a single particle traveling along a path, then switching to another path. Perhaps you can get some use out of such a setup? The first path could be the travel to the door and the second path could be entering?
