At the simplest level, just having a MAT pose for P5/P6 so that bumpmaps are loaded better-than-default is a good idea. The next step is to use procedural shaders where the materials grouping allows it. I quite often replace texturemaps for metals with shaders from Mapps' collection. You can do the same with leather. I think as long as EF are selling Poser Artist there's going to be a market for P4-compatibility, and there will be the P4 render engine available in later versions. But some of the P5/P6 features really need better support from EF. The manual is full of holes, and dynamic hair and clothing still seem to be something of a black art. DAZ Studio -- let's wait and see. I know some people are using it as a tool to prepare scenes for Poser, because one or two of the add-ons do stuff that Poser doesn't.
