I guess this is an endless debate.

I still think that a "Poser compatible" product should pay attention to how it renders in Poser. If it uses a reflection strenght of 100% on almost all materials being wood, marble or wall paper, it is plain wrong. Same goes for displacement and bump setting which are set to 1.5 cm. Light sets which are missing in one program and are present in another program - the lights may have to be adjusted to the users preferences but the position of things like spot and pointlights are usually fixed for any program

If you have to adjust 150 materials on a set of props for simple things like these, it is not a trivial thing to do. Not difficult, just tedious and taking a lot of time which should not be needed.

Some vendors do excellent work and even though I might not agree with their choices, I absolutely appreciate the effort they are doing in making it work in Poser.

There used to be much more attention to things like this in the DAZ store by the quality assurance team. That seems to have gone now
