Combine meshes?

Hi all,

I have an object that is made up of multiple meshes. I want to combine all of these meshes into one mesh so that I can shade with transparency correctly. I have tried using, but that just makes my character disappear. This might be because my mesh pieces are moving? I’m not really sure.


Found an answer to this, needed to call mesh.optimize, and my transform needed to be modified since the example assumes the object is at 0,0,0.
