Answer to 01. If you have amazing materials that only work in Poser, why not use them. Just because Studio cannot use them does not mean that those materials shouldn't be used.

 

Answer to 02. With all the materials etc. there is not enough time in the day to check which do and don't work with  STudio.

 

Answer to 03. Why should someone who just works in Poser, have to make those items Stusio compatible? It's down to the content maker as to how they make things.
