Join Eric Keller for an in-depth discussion in this video Applying 3D procedural texture nodes, part of Creating Textures and Shaders in Maya.
The 3D textures found in the Hypershade are similar to the 2D texture node.…These are more additional procedural nodes that you can apply to the channels of…your shader networks.…The main difference is how they are mapped to the surface.…By default 2D texture nodes, whether it's a file texture node or Fractal or Ramp…or so on and so forth, use the UV texture coordinates to map the pattern created…by the node to the surface.…3D texture node uses a special 3D Placement node in order to map the pattern…to the surface, and this can help you get around some of the drawbacks of using…UVs to apply procedural texture nodes.…
So for this copper pot shader, I have a 2D Fractal texture node applied to…the Reflectivity channel, and for the most part this looks okay, because you…don't see any of the problems that can be caused by doing this, because it is fairly subtle.…So for example, the Fractal pattern seen on the surface of the pot looks fairly…even and I think part of that is just because we're getting little bit lucky…
