# how to make a weapon shatter when hit

I am animating a fight between two characters and I ran into a scene where I wanted one of the character's weapons to shatter like glass when the other character slices it. I have used a few things that supposedly do this including the cell fracture add-on but it did never finishes they top part of the sword , but the methods I've found do not work with a sword such as a katana.

I'm hoping for a way to either make the cell fracture work or find another way to break the object like glass.

here is what happens when i try to use the cell fracture on the katana:

Here is the original katana in edit mode:

• have you tried the cell fracture addon? – aliasguru Aug 16 '16 at 5:41
• Could you please specify what 'it does not work' means? It's unclear at the moment what you're trying to achieve. – aliasguru Aug 17 '16 at 10:15
• there is a youtube tutorial series here on how to shatter a coffee cup, it might be a similar effect to what you're trying: youtube.com/… The special thing is, they use the Grease Pencil to define the shard distribution, so there's a lot of control for the shatter effect. – aliasguru Aug 17 '16 at 19:44
• add more detail as to how the cell fracture is not working – A guest Aug 18 '16 at 23:03
• Cell fracture may create result like that when the original mesh is non-manifold. Enter Edit mode, choose either Vertex or Edge selection mode and run Ctrl+Alt+Shift+M. If something is selected most liklely it's the problem. – Mr Zak Aug 24 '16 at 8:59
