Thanks fgeorge, it worked. I suggested that it was something like that, but I was in a big hurry and the documentation and samples really suck. You saved me a lot of hard work. I have more than 1000 renders to do, and without the script that would have taken me a week or two. No I ran it during one day, completely automatic. Lourdes, I probably can do it like that, but right now, it is not what I need. I'd also like to keep it as simple as possible, since this is my first try at python (in any form) and I don't have time to get bogged down on syntax details right now. It would be very helpful if it was possible to record macros which could then be edited and adapted, much like it works in Office or UltraEdit. It would reduce much of the hassle and lower the threshold for starters in python. If it were up to me, they would've used VBA instead. It is cheap and easy to include (I've done it in my software to make it user extensible) and it is widely known and easy to learn, while still being powerful and object oriented. Some documentation of the poser object model would be nice. Perhaps a project for someone with spare time and nothing to do? /Troberg
