Particle Point Emission

[Yassine]

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!

have you tried the foreach sop?

take a look at the file.

It's very slow compared to the old one, and that's probably because it's doing the same operation for each point in every frame.

I don't know why it's not working for the point #0

Thanks Ehsan,

I tried using the Partition SOP before the ForEach SOP for each group and the emission was working as well, but I couldn't then make the Add SOP doing the job.

Your solution is better. There is definitely something going on between the first and the last point, because the numeration of the points is overlapping in the latter.. I'm still trying to figure out what is it.
