Having a separate collision object works, but with fast movement I still get a lot penetration through the mesh.
Apparently it can be done better with a forcefield but I cannot get it to work like this https://www.youtube.com/watch?v=OeFZbp_UC0o
I have my emitter mesh with the hair particles and a second mesh that I set as force field with the same settings as in Video 1, but the force field has no effect on the dynamic hair. What am I missing? Maybe a setting in the particles system itself?
