using them, but rather do it now that I have the chance still. Highlights: * Wood and Marble merged into a single Wave texture * Clouds + Distorted Noise merged into new Noise node * Blend renamed to Gradient * Stucci removed, was mostly useful for old bump * Noise removed, will come back later, didn't actually work yet * Depth setting is now Detail socket, which accepts float values * Scale socket instead of Size socket http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/Textures
