The characters in my game are small robots whose hands, feet, and head are connected to the torso via beams of energy. When the energy level hits zero I want the beams to turn of and the pieces to become physics objects. Is there a way to achieve this with a skeletal mesh? ---

Hi Skuvnar, One of the easiest ways is to change the Skeletal Mesh for mesh pieces that are in the same location and rotation at the moment it’s destroyed. Take a look at the solution that this user came up with. > **[What is the best way to blow up a character to pieces](https://forums.unrealengine.com/questions/79761/what-is-the-best-way-to-blow-up-a-character-to-pie.html)** > > Hello, I realy appreciate some one giving some thoughts and examples if you can, to show how to deal with this situation: I have a character and if he is killed by a projectile (explosion) he will be blown into pieces that will use physics, but i...

#Physics Asset I do exactly what you describe i this video! As long as your mesh is not contiguous / the various pieces are not connected, you can simply use your skeletal mesh physics asset! just delete all the constraints and you will get the effect you want when you run simulate in the Physics Editor! #No Extra Work No extra work is required! All you have to do is delete the constraints and you are done! You need a physics asset anyways, so dont do extra work! You can just delete the constraints in the physics asset and turn physics simulation on whenever you want the robot to break to pieces! #Videos!

And how do I delete the constrains? ---

I just did a small tutorial about it: [![](https://d3kjluh73b9h9o.cloudfront.net/original/4X/6/9/e/69ec9a52271fee4433504f31fd0fce1ae2e65e4b.jpeg "Use skeletal meshes as destructibles (Unreal Engine 4.10)") ](https://www.youtube.com/watch?v=-04qNDKFFq0)
