Hi there odforce! beginner here.... I have a bunch of particles shooting out of a center point in all directions on a surface. They are rotating along their velocity. Now I am trying to randomly offset their orientation but have them still rotate along their velocity. I guess I need to get some vector from the quaternion and multiply it with a rotation and feed that back into the orient attribute. But I cant get this to work. In the forums I found that the old POPs have an Angular Velocity POP. I guess this is what I need to build in DOPs for my setup. I commented the hipfile, I hope the question becomes more clear. There are spheres instanced onto the POPs so you can see the rotation best in wireframe. Thanks a lot for looking into that! oliver
