I am trying to map a high resolution bump map on a UV sphere, I am using a UV map, and I get this result:
What causes the renderer to make these huge blobs? This should be a moon, far away and big (distance is about 500, size is 300 blender units), my bump map is 3840 x 2160 Pixels TIF file (I got the same result with a half resolution bump map, too), UV-mapped to the sphere. Mesh is set to smooth, Subsurf is set to 4 subdivisions, and the node setup is as follows:
What am I doing wrong?
Thanks for the help.
