Bump map

Hi.
I have already searched in the forum, but there is no answer for this.
I have built a model in Blender and imported in Fusion 8 (not Studio version). I can't pipe a bump map, although I am able to change materials.
I have already tried by exporting from Fusion with .fbxexporter node and reimport. Also have added more subdivisions in Blender.
Any clue?
Thanks
