You cannot directly import lightmaps created in other programs to be used with UE4. There is no way of assigning these.

If this is a texture that you’ve baked you can apply it in your material that is combined with your other textures like your Diffuse, Normal, roughness, etc.

You can try plugging the lightmap texture into a multiply with a set scalar value. The multiply can then be plugged into the Emissive Channel in the Material. You can use the scalar value to control the brightness of this texture in the emissive to tweak your lightmap texture to be as bright as you’d like.

I hope this helps.
