I am trying to create a scene where several vehicles travel across an uneven surface. To get the effect I'm looking for I put the vehicles into a hair particle system, however I dont know how I would get them to travel across the surface in a decent manner without having to animate each one individually.
Pretty much all I want is for the vehicles to travel in a straight line forwards over the course of a few seconds.
Is there any way to make the particles travel across the surface in a decent manner?
EDIT: After following the advice of Lemon I have something similar to what I was hoping for, however there are still a few small issues I need to resolve before its finished.
In addition i'm wondering if there is a way to have one of the vehicles to be less common while being in the same particle system or whether it would need to be in its own.
I'm unsure as to how to solve these issues, and am hoping there is a way to without having to have each vehicle be its own mesh.
