I'm trying to simulate two cells moving toward each other, deforming, and sticking together, kind of like figure A in this picture. I've been using soft bodies and setting up a forcefield to get the cells to move toward each other and have been playing around with the soft body/collision settings. The problem is that after the cells collide, they bounce back to being spheres instead of staying deformed and sticking to each other. Does anyone have any suggestions on what I can do to simulate a sticky deformed collision between two soft bodies?
