Hello, can you explain my current problem… I create character in blender, I made it’s hair using the hair particle system, I converted the hair into a mesh using the “convert” button.
Now, if I animate my character (I import a .BVH file for a walking animation) the hair is not following the body, it static in the scene, and the body walks without it 
:(, what to do?..
You need to parent the hair mesh to the armature that controls the rest of the mesh.
No blend file, or images to look at - so I cannot say more than that… Blend files should be uploaded to pasteall.org/blend then post the link here, Images are also useful to help us help you.
Cheers, Clock.
Well I tried but… If I parent them it’s work but just in Blender as a preview but not in final render animation…
When you convert hair to a mesh by pressing convert, blender converts it to a series of edges, which have no volume or faces and cannot be rendered as is. You would then have to convert the edges to curves, and then use a bevel object or similar. That said, you probably should not have converted them at all, hair system can be baked with dynamics to bounce around like hair.
But this is wild because when i render human before import .BVH file hair is still on head but when I import the file I can’t rendered hair
The particle system needs to be below the armature in the stack.
Thx very much, it’s work
