Stop hair from falling through emitter mesh I have a simple sphere with a hair particle system on it. When I add hair dynamics, the hair simply falls through the mesh. 

I would like the hair to fall around the mesh and collide with it (both the emitter object and other objects). I have read many other posts about how to get the hair from falling through the mesh, but all of them simply suggest turning on collision on the mesh ... which I have tried to do. 



I am new to blender, so I am sure I am missing something obvious.
Enabling collision on the emitter doesn't work on the hair system, yet (2.77). 
To achieve collision, you have to do a workaround with a collision mesh:
1. You have to duplicate your model. 
2. remove the hair particle system on the duplicated Mesh.
3. Exclude the duplicated mesh from rendering (uncheck rendering in the outliner). 4. Enable collision on the duplicated mesh.

You may need to tweak the settings a bit though.
