Add lightmap to mesh after import?

Hi
I've been playing around with UE4 and I relatively recently discovered lightmaps (new to engines) and I had already imported a lot of my assets. Is there a way to make a lightmap in Maya and attach it to the mesh already imported?
And is there a way to change the already assigned UV's for the textures?

Thank you

Typically it's best to use UE4 to generate lightmaps, your second UV channel will be used for lightmaps, you can just create a new UV for the light map and reimport the asset. Using the Texture Coordinate node in the material editor you can change what UV set is used.

Cool thanks ZacD, i'll look into this.
