Can you help me out? I'm getting this message in log: [Shelf] "C:/Users//Desktop/dirtycam_desert_metal.spsm" cannot be imported as a smart material. - I'm actually having the same message for many materials. Maybe half of all the materials I try gives similar result. I also tried to drag and drop it in the Material section just to make sure.
jodesserres, after you downloaded the material or smart material, go to your SP program then open your download folder and select the item you want to drag and drop, if it is a material then select the material tab and then drag and drop the item, then select import to shelf, same goes for the smart material but make sure you select the smart material tab.
Thanks for the smart material
