Specular highlighting lightwave

How can i add a specular map to a DTS model using lightwave. It currently says it doesn't support it,well, it does not say it does, nor how. i am hoping that just because its an old doc.

BTW, Dave, your exporter doc needs some TLC =) lol. Its great, but i think its missing things from the newer versions of the exporter. I cant seem to find this info anywere.

Thanks ahead of time =)
