Merging static objects.

Hi i am wondering how to merge multiple static objects into one object. I have a some guardrail models I would like to merge, once they are set up in game.
thanks

 

The only way to do that is to edit the mesh in a 3D modelling program.

 

What about the export Dae option? Would it be possible to select all of the meshes and export all of them as one model. Currently i have tried this but no luck, but maybe there is something I am missing?

 

I don't believe that's possible.

EDIT: I just tried that feature. I get a dae file, but It won't import into Blender.
