If you'd still like to use that shading network, you can fake it:

Render out a nice 512x512 top view of a plane with the texture. Save that image and use it as a texture for the actual objects. A few different varients of the shading network will give you a nice start to throw on some of you're objects.

I find when creating a scene (not just an object) having even minor texturing helps me visualize the whole thing. But maybe thats just me cause everyone else seems to be waiting (except Natalia)
