Oculus Home custom emissive materials [MAYA]

Hi! I've been trying to export a scene from Maya in order to import it inside custom Oculus Homes... (via fbx to gltf) but no matter how I try it, the object doesn't emit any light at all. I tried it with a shader, lightmaps (erx to png map) or/and the 2nd UV map. No way... so a little help could be great. 

Thanks!
