Exporting Props with normal and specular maps?

Dear Daz folk,
I really only use Daz to export things for use in iClone -- but I've bought a TON of stuff for this purpose. What happens is that after I export (either OBJ or, if it's a figure-rigged prop, as FBX) I get the diffuse maps just fine, but no normal or specular maps or opacity -- basically just the diffuse, even though those other maps ARE provided (if I go into the Textures directory for that prop or environment I can see all the maps).
What I then end up doing is loading each and everyone in manually, which is a huge PITA. So I thought that perhaps my software just isn't importing properly. But when I go into Daz I only see the diffuse map loaded for each prop. It has sliders for the normal and opacity and specular and metallic maps, but no maps themselves. So now I'm thinking that perhaps those maps aren't being exported because Daz isn't loading them in in the first place.
So I thought I'd ask you good people here -- am I just plain ignorant (well, I am, but that's kind of besides the point) or is there something special I need to do to make sure ALL the maps get loaded. I'm just, for the most part, using the default "Load All" DUF that most developers provide for each environment or prop, and I just assumed it was loading all in. Or is it really all loaded in and not exporting properly? Or something else I just don't understand?
TIA for any assistance.
