Hi Noseman,

Ive attached my scene file, im just trying to spawn a bunch of boxes and have them stay facing directly toward the camera, but I cant stop them rotating.

Do you happen to know if theres a way to lock off rotation in a rigid body sim?

I've tried Bullet and the new sim engine and played around with anglular damping and tried increasing samples substeps etc, but no matter what there is always a little rotation on collision.

Or is there maybe a way to use forces or look at camera or a direction or something?

I also thought i might be able to bake the clones as alembic then just remove their rottional data, but that wont work either, cant bake the clones because they are spawned by particles.

Any ideas?

Thanks heaps for your help!
