Is it possible to change the Mesh of an single Object instance at Runtime?

Sorry for my bad english

I want to be able to:

  • Change the mesh of a single object instance at runtime
  • Not modifying the meshes of all objects that are using it.

Thanks in advance

There should be the member SetStaticMesh

Because my ultimate goal was to make a tiled map I already found a solution for this problem.
I will simply switch from meshes to brushes thanks alot to everyone who tried to help me!

Even thought I found the answer by myself thanks alot for trying to help me.
