Hi Michael,
I follow now.
There is now another element involved when modeling in MoI, material assignment.
What I mean is, I haven't used Model/Render packages much, my thought was you model, then assign materials after you finished the modeling project.
In what your saying with styles, I will be assigning materials as I'm modeling, on the fly.
I don't know if this a good thing or a bad thing I'll have to try this approach with my next modeling project, concentrate on modeling alone and then assign the materials or assign the materials on the fly as I'm modeling, let us see.

As long as you include the inherit switch in the .ini :)

Cheers
