Velocity from curve tool

Hello all, this is my first time posting on here so greetings. I have been working on a tool that takes an input curve and adds velocity to it for use in a Pyro sim (also FLIP but first getting it to work with Pyro). I have been working on this tool to help give the artist an easy way to direct a Pyro sim along a curve.

Here is an example of how it is currently working:

Here is a screen cap of how I have implemented the use of the tool:

I'm also including my otl and an example file.

I would like any feedback as to ways to improve the tool or other/better ways of accomplishing similar effects. I greatly appreciate it.
Thank you much.

I cross posted this on odforce and was given a suggestion to use Vops rather than scattering points in a volume. After reworking the tool in Vops I am very pleased with how much faster it is cooking. I am instead within the Vopssop taking normal tangents and displacing the points along those vectors which in turn gives me more control.
I still of course welcome any feedback, suggestions or critique.
Thank you.

Here is a link to the odforce post:

I have not posted any more tests yet but a screen cap of the tool use can be found here:

Looks good, thanks for sharing it. I'm thinking of adding some velocities to underwater particles and this will help a lot to understand how to implement it.. this vops thing feels powerful (coming from maya :roll: )
