I assume that many of you are familiar with PBD (position based dynamics). I want to design a scene that has papers floating in a space. However, when I put the paper mesh in the PBD Niagara system, I had a collision issue. As the number and size of papers increase, they overlap with each other. This is an unwanted result for me. I would really appreciate it if you could help me. I hope there is a solution to fix this. Thank you.
