So continuing the flocking theme, here's another setup using Bullet for collisions and note the nifty trick for rotating the bullet objects in the direction of travel. :D

Johnny, I guess I solved at sop level using the same dihedral function but applied to @orient attrib . matrix3 m = dihedral({0,1,0},@v); @orient = quaternion(m); - the wiggle vex in the scene is pretty cool!

Before the DOP? But that would mean the they wouldn't auto correct their up axis after collisions, wouldn't it? Or do you mean after the DOP?

Unless you do this in DOPs you don't get the correct collisions. After DOPs you just need an up vector and a copy to points will align automatically. :)

I first got to know 'pop flock' dop, I tried to replace 'pop fluid' (for H17's), but it's a strange form lol. anyway cool workflow!! [@v > attrib-blur > Up-vector resorting ] it was interesting.
