So, i've spent the last three hours trying to figure this out.

I have a very simple particle system with particles being birthed from a circle and then I copy disk like spheres to each particle.

The problem is that I can't get the disks to be copied with the proper orientation. The strange thing is that on particles birthed to the left the orientation seems fine and the particles on the right seem to get twisted.

I've tried EVERYTHING within my limited knowledge. Even animating the rotation of the source circle along the Y axis seems to affect the “twisting”.

here's a screen grab so you can see what i'm talking about.

this seems so simple. I'm sure there is something real stupid i'm missing.

best,

See this great post by wolfwood. Contains almost everything you'll ever want to know on the subject of orienting ‘things’ to points:
