Not Cycles online material plugin??

given that my system does not like the Cycles Renderer i am needing a way to get access to a few materials but the online material lib plugin (which is buggy) is cycles only.

can somebody explain to me how to make a good silk material and a good metallic fabric material?? (bonus if these can be baked)

Oh and i have FGI so no search for X answers if you give a link it needs to be to an actual useable blend file.
