Being really new to rendering things, I have little knowledge no how things work in Blender (texturing/rendering wise).
Watching Firechild's tutorial on how to create a golden ring.... he does have Diffuse BSDF and Image Texture nodes available.... which I do not... (there is only 'Image' node)
Downloaded some model from Blendswap and these nodes are there....
My question is what exactly affects the selection of nodes available to a particular scene? Does it has anything to do with the materials/settings used?
Thanks for your reply!
