I’m making a short film with a character who has hair and a skirt and is standing in a wind simulation. I’m having trouble with the particle (hair) simulation. The particles move through the mesh, as you can see in the following image:
I don’t have the same issue with the skirt. It works perfectly.
I have done the following in setting up the hair particles:
-
assigned a collision modifier to the character’s mesh.
-
made sure the Hair modifier in the modifier stack was below the Armature and above the Subsurf.
-
tried putting the Collision modifier in different orders in the modifier stack, but found that on the very bottom worked the best, even if it didn’t solve this particular problem.
-
increased the Root size in the Cycles Hair Settings panel in the Particles editor in the Object window.
-
in the Hair Dynamics panel of the Particles editor in the Object window set Stiffness value to 1.0.
-
in the Emitter settings in the Particle Editor, set segments to 6 or higher (current setting is 7).
While doing these have solved other problems I was having, I don’t know the magic bullet that will fix this particular problem. Maybe it has to do with Blender’s capabilities, but this seems like a really basic thing for anyone wanting to make a hairy character be present in a wind simulation.
