Ok awesome. Thank you much. One question though how does one go about adding points to a point group? Would declair a pointer to a pointgroup then add each point as a *GEO_Point? Does it act like a vector as far as data structure goes?

Hey all,
I have been having issues with deleting dead particles in a GEO_PrimParticle system. I will refer to the SOP_SParticle.C example file. When using this node as the particles reach the end of their life they are marked for deletion by use of deadParticle(). All of these marked particles are then deleted by deleteDead(). The issue I have run into is that this only deletes the vertex not the point. The points still show up in the viewport and just stop moving. I am trying to figure out how the points and verticies can be deleted. I have been searching and trying to figure this out for a bit now so I am posting on here because I have been unable to figure it out. Any help or suggestions would be greatly appreciated. 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.

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

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.
