I show you a video of the situation: https://youtu.be/MAMXrpBc2LU
Question 1 is - I have a sphere with hair that I try to collide with a square, the square has collision in physics. For some reason the hair does not interact with the square, tell me if I am missing any parameters.
Question 2 is - why is the simulation recalculated when I go back to the time line? how do I prevent it from being recalculated and consuming memory?
