Particles following splines

Howdy peeps... Quick question - Is there a custom Particle Flow operator that moves particles along a spline path? It seems it would be such an unbeleivably useful operator since the good old "path follow" space warp doesn't work... unless I'm being incredibly stupid (and that has been known to have happened)

Otherwise, huge "find target" trees end up being created which ends up becoming really messy.

Oh, to be able to know maxscript...

I am truly stupid.

edit... 'although speed by icon' and speed by surface still don't seem to be the neatest way of doing it... but some would say that about my my house

i use speed by icon and link it to a spline using the path contraint quite often
using this in conjuction with blur's cylinder script or ghost trails, you can produce some pretty cool looking stuff

Do you know of a way to have particles birth on a spline and have them shoot out from all directions based on a face normal to the spline, even if there is not a face to have it go off of. In short, particles emitting from a spline.

Thanks,

R.

BigRanS123, the best way I can think of would be to reference the spline. Add a renderable spline modifier. Hide it from render and emit from that. Otherwise you would probably have to script it.

You need to give it a normal alignment first . Select all the verticies on your spline and apply a uvw map. to the stack. Not enough emmitters? Refine your spline segments. Just got a sweet idea for a set of whips from this post for NWN. Thanks ^_^

I've been playing with this for a few minutes. You don't need to select the vert sub-objects you can just apply them to the spline. But in your birth operator you still need to emmit from selected verts. It then spaces the particles along the spline evenly between the verts. So vert placement is a concern. Might want to use beziers, to get the correct curve and vert placement.
