inspired by the cg cookie tutorial (https://www.youtube.com/watch?v=wWEwxtu9gGc) i want to simulate traffic on a road with two lanes. lane 1 going in 1 direction, lane 2 going in the opposite direction.
but i am always stuck at a problem with the curve guides force field.
my approach until this point:
- i take a bezier curve as my base, model the curvature and extrude it in the geometry tab to get the with of the road itself.
- to get two matching traffic lanes i then convert the curve to a mesh, add some loop cuts where i want the individual traffic lanes to be on each side of the original road curvature.
- then i separate both loop cuts into individual objects and convert them into curves again. this way i get perfectly aligned traffic lanes.
but here comes the problem.
i place a particle emitter at the starting point of the curve and set the curve to be a curve guide force field.
but then the whole thing always freaks out and the curve guide doesn’t seem to work at all.
does anybody know a trick to make it work?
has anybody encountered similar problems with converted meshes as curves before?
