Combining two bump maps in Maya

Sometimes you want to combine two bump maps in Maya. How to do this isn't entierly clear, however. What you need to do is the following:

Let's say we have got two textures, textureA and textureB. We want to use them both as a bump map in maya.

• Connect the two textures to a bump2d-node each
• Connect one of the bump2d-nodes to the other.
• bump2d1.outNormal -> bump2d2.normalCamera
• Done!

The outNormal and normalCamera-attributes can be Hidden, and if you don't see them, check Left Display->Show Hidden and Right Display->ShowHidden in the connection editor.
