So I think you are confirming my suspicion that if you want to change one or both surfaces on either side of a complex profile wall from what the building materials / fills are set up as in the profile then you must duplicate it and then change the materials / fills in the complex profile duplicate? It doesn't seem to make using complex profiles as efficient as I'd hoped.
Do you have any links for more reading on the last point you make as I'm not sure I follow?
Also, while I've got you, another thing I have had trouble with with regard to surfaces is that if you duplicate a surface and then customise it, you seem to only be changing the OpenGL settings and not the CineRender settings. So when you go to use that 'custom surface' in the surface painter you end up painting in the unchanged CineRender surface. I don't see how you can change the CineRender surfaces and is there no way of 'painting' with OpenGL created surfaces?
