"New" Materials have already been added and need to enable certain channels (in the AM) and then set the channel properties.  Using GetChannel() works with Color channel, but setting BASECHANNEL_TEXTURE applies the texture to all channels.
What's the basic technique for enabling and setting particular Material channels?

Okay, got a handle on the the Material channels.
To enable or disable (replace DescID with appropriate channel and TRUE to FALSE to disable) :
baseMaterial->SetParameter(DescID(MATERIAL_USE_COLOR), TRUE, NULL);

Some channels cannot be set using the BaseChannel - such as the Specular channel.  Instead of getting the BaseChannel and setting the BaseContainer data, use baseMaterial->SetParameter() as above to set the various channel parameters:
baseMaterial->SetParameter(DescID(MATERIAL_SPECULAR_HEIGHT), 0.5, NULL);

for instance, sets the specular height to 50%.
