Hello,

I tryed the tutorial at 3D BUZZ to do an exercise with the Force sop.
Al fine an well until I tryed to modify it for my own learning purpose.

PROBLEM: As you can see, metaballs are copied along a line of ten points and these metaballs are used as a bounding box in a group sop to group all point comming from a grid and intersecting with the metaballs. I then use this group for the animation. BUT what do i need to do to make ten groups containing each of the copied metaballs seperatly. So I can animate them seperatly on different $F in stead of all at once.

The file is attached, thx in advanced.
Cheers.

You can insert a Connectivity SOP after your delete SOP. This will create a $CLASS attribute that you can use.

Great! Thank you very much Edward.
