Quote - a ds shader show up in your my library under presets and shaders labels.

you use them the same way you do mat pose/changing textures.

select the item in the scene tab, and in the surface tab then select the shader and apply.

 

Thank you I will experiment with this. I confess I still am uncertain about how to go about it. In the SURFACE tab are the Shaders found by clicking next to the Diffuse slider to bring up a long list of textures? Otherwise, I do not know where to locate the shaders in DS' Surface Tab.
