3DSMAX lightmapping with V-RAY

Hi, I would like to render a lightmap with V-RAY in 3dsmax render to texture.
It creates a lot of files, but I've no way to match them with the .X or .3DS I export from 3dsmax.

Do I have to remap all the textures on the model? Or is there a serie of actions I can do to include the lightmaps into the x. so it will export correctly?
