Hi all,

I'm trying to figure out how I could make every single emitting point from a surface an independent source.
Lets say I have a grid of 6 rows and 6 columns (36 points) and I emit straight in the positive Y axis. Using then add SOP by Group and skipping every Nth points with N = to the number of emitting points, I get single straight lines.
Creating a collision event and killing the velocity of the particles I can stop them once the first particle collide with a surface set opposite to the emission location. This means that all the lines stop anywhere they've got to, even if their tip hasn't reached the collision surface; of course because they belong to the same Particle System.
How can I, say make every single point of emission independent so that every single line stops when its tip collide?

Here's a file with the example I have described.

Thanks for any input!
