I’m using Blender 2.68a on Windows 8 with an NVIDIA GTX 660M and am having an issue with the Cycles render / node editor.
When if I combining a Diffuse BSDF node + normal map with a displacement map in the Material Output, the displacement seems to be cancelled out by the normal map. It works fine with just the displacement and just the normal, but when I try to combine the two, only the normal is used.
I’m pretty sure I had this issue in recent previous versions of Blender too.
Attached are some images of my node setup and a sample blender file which replicates the issue for me using the Rendered viewport shading.
Does anybody have any idea what’s going on here?
