Most of the current Python scripts were written for Poser 10 and have NO clue about the new Render engine. When Poser 12 comes out there will be 2 types of users 1: will be those of us that already have Poser and therefore will be able to run the current python 2.7 scripts and 2: Users who have never had Poser and therefore won't know about all the OLD scripts. Personally I have Poser 5-11 still running on several computers and if I really need to use an old script just fire up the proper version and have at it. There is no requirement that says you can only have 1 version on your computer.

At some point Poser is going to have to move forward and leave teh past behind. In some respects poser 11 does that since a poser 11 scene can not be used in Poser 1 if it has any of the new features used such as SuperFly.

Poser 5, 6, 7, 8, Poser Pro 9 (2012), 10 (2014), 11, 12, 13
