Im stumbled on what I think must be a super simple setup, I do seem to make it way more complicated than I think it need to be. What I want to create is a saturn ring with asteroid particles. The ones closest to the middle I want to rotate faster (easy by scale it by distance). Thats basically all I want to do. However I thought that aligning the direction to the centre, and just do a velocity on the X would to the trick, so the particles keeps poiting towards the middle and just moves on X in their local axis, however everything moves as on unit, just in one direction when Im doing that. This is what I've done now. Its messy, and the particles tends to move away from the center as I increase the velocity, and I have a null to drag them back.. Simply not a nice solution. Anyone know of a "cleaner" way to achieve the same thing?
