I'm working on simulating very simple cloth physics using godot's particle system, and I think the final key to this puzzle is having the particles set their rotation only once - when they are created. However, when messing with the angle property of a particle material at run-time, it affects all particles all the time.
In effect, I want the particles to be looking at where the origin was when they were created. Currently, they all just look to where the angle property tells them to. Is there any way to get the effect I desire?
