Piping Mesh Data back into original Just wondering about Blender AN workflow. Normally I have original mesh and do something and output as NEW mesh. 

Wondering, if I actually plugging in whatever process back to original mesh, is this actually possible?

Say, perhaps I am pushing the vector of Suzanne head... the output currently is the NEW Target object.

Is there a correct way to do this?
The correct way to do this is to use a source and a target mesh object. Unfortunately it is not possible (well it is, but not useful in most cases) to use the source object as target.

The reason is that the original mesh data is lost when you overwrite the source. There is no way to get it back.
