View Full Version : Animating particles at constant speed

is this possible in Lightwave?

Well, you can give them an upper limit for speed. Then, if the forces acting on them were overblown, you could be sure that most of them would be at that upper limit most of the time.

the case is im animating a bunch of cars for a race, the road is straigh and the will need ride for at least some km. I found difficult to animate the particles to be at that speed constantly along the distance...

Just reading and problem solving...

Make a string with the same amount of points as cars.
Move that point along the line
- apply some kind of dynamics: texture, wind, etc., so that the points are randomized a bit.
- Editfx those points.
You then have somewhat random paths of which you can edit along that long distance.
And attach the cars to the paths, not to the points.
A thought on passing...

You can also set particle resistance to 0 to keep the moving forever.

If you use wind, that will move the particles at constant speed. Wind can be a variety of different shapes, the one I use the most is Wind set to Path, where the path of the wind emitter is used as the path the particles follow.
