Quote - No- it is Photoshop that is papa.

Neither mix brick nor blending nodes is the correct way to do it IMO, except possible at the concept stage. Sergio Martinez(Xurge) showed at the seminar he held the 8 and 9th June how he organized everything with the help of one big Photoshop master file (well two actually). All orderly and distinct placed on seperate layers

Material areas, borders, bump, displacement, ornamental patters, even down to stiches, everything had its own layer and could be manipulated and changed with a click. (blend styles as well as displacement). That made blender and mix nodes look like a toy. And the finished maps could be used in any application, not only Daz and Poser. Its all about being organized.

Yes, you can set up a psd file with maps for all the different aspects you want to include. This is a different approach and they are both valid approaches.  

When I create texture maps for something I do it all on the one psd file and have maps for displacement, specular etc in the one file.

There is no one right way only different approaches to suit what you are trying to achieve. 

 Edited to add...I actually use folders for different maps and group the different layers together that makes for easier editing later on.

Cheers
