You can save a Material Preset (File>Save as>) which works in D|S, and includes all settings, or you can use PoeWork's mat file writer to save a Poser Mat pose or material collection, which won't save everything in a form that can be read by D|S and may need tweaking for use in Poser. The PW script is free, but I don't have a link to hand - check my sticky thread listing free scripts in the D|S Freepozitory forum at DAZ.
