You need to create and connect a materialInfo node to your shading network.
Maya does this for you with the built-in shaders, but expects you to take
care of this for custom shaders.
1. Trace the material's ".color" attribute upstream to find the texture
node.
2. Create a materialInfo node.
3. Connect the texture's ".message" attribute to an element in the
materialInfo's ".texture" attribute:
connect file1.message materialInfo1.texture[0];
4. In the Material's Attribute Editor, expand the "Hardware Texturing"
section, and select "Color" as the texture channel.
Don't want to do this manually everytime you create a shader? Create
callbacks in your shader node - e.g.
MNodeMessage::addAttributeChangedCallback and
MDGMessage::addNodeAddedCallback - to wire this up for you automatically. Be
careful though, as there are several gotchas waiting for you. I've spent
over a year chasing this one, continually finding little exceptions and
special cases where my custom shader must (or must not) intercede to
maintain visual acuity.
