I'm having problems with making realistic texture. Following Blender Guru tutorial from a year ago I made a plane with custom material using nodes and few images from CrazyBump.
For some reason internal material preview shows my material exactly how I want it, but render is different (both full render [F12] and render preview). There is some data "getting trough" because the plane have a different colour but that's it.
I tried manipulating the nodes, subdividing a plane but nothing seems to work.
Is that just a wrong workflow, or maybe a bug? Am I missing something? Would appreciate any help. :)
