Odd Bump/Normal Map behavior with Texture Nodes - Blender Internal So I've run into an issue that is really confusing me.  I'm trying to set up a material that gets bump mapped by a texture that uses nodes and getting odd results.  Here's what I mean:

Bump mapped with normal clouds texture:


Bump mapped with same settings, but texture that uses nodes:


That same node texture, but applied to color instead of Normal:


Hopefully that makes the odd behavior clear.  As you can see, it influences color fine, but if I set it to Normal the entire object looks smoothed out.  The texture in question is just a simple mix of clouds and noise - I've tried both individually and they work fine, but not when the texture is set to use nodes.  

So, in summary, what about having the texture use nodes makes it so that it doesn't influence the Normal of the material properly?

Here's a link to the .blend
To output normal data, you need to use the Normal socket on Output node. (Be sure to also enable Normal setting in Influence)
