Timing particle bursts to object rotation

Mark, thanks for posting that. While it's not the ideal solution, it will do 
what I need, and it has opened my eyes to the pFlow freebies. I wish it 
didn't use the second Emitter as the sensor, but I shouldn't complain, as it's 
solved my problem.

Thanks again, you've been a great help :)

My solution to this would be to use emit from a mesh, only selected verts. 
Then have a mesh attached to the flywheel that passes through the steam 
emission area. Use volume select on that mesh and use a box as the volume in the

emission area. As the mesh passes through the volume its verts become 
selected and particles then emit from that mesh.

It only emits when the mesh is passing through the steam area, and it does 
not need any extra plugins to work. It should be just fine with plain Pflow. 
Only problem I see with it is that it would pump out steam continually if 
the mesh stayed in the volume box. But there is probably a cunning way 
around that.

I gave this some thought a while back, as I considered adding a steam 
particle effect to my Hudson train model I produced for my CGA mech modelling 
DVD.

Chris, that sounds like a great idea. Thanks for posting that solution! :o)
I shall try that first thing monday morning when I'm back at work.

Thanks again,
Nik
