Hello everybody! First, I like to thank Steve for drawing my attention to this Forum. All I can say, is that Im sorry you didnt contact me right away, I would have been glad to help each of you right away. Lets start with screen redrawing. First of all, Read The Manual :-). It says there you have to give the program a bit of screen space to itself. That way, you can let the program work, do renderings all the while, and still get the program back without trouble when Poser grabs focus when it has rendered. If you dont do that, it only SEEMS as if your computer slowed down- only seems though. The reality is, that the Creators have taken ownership of most globals. Posers rendering engine is unaffected. Everything you need to do to your lights is done via the Creators. Once you exited from the Creators, everything is back to normal again. So, recap: start up the Creators, dont touch buttons, sliders, menus in Poser, but do everything from the Creators, using their buttons and menus only. They have been designed to do this for you. Render as much as you want- as long as you keep a bit of screen free for the Creators- 20 or 40 pix will do the trick-, so you can click on them to get them back when Poser had grabbed focus after a rendering. Go on working the Creators till you have what you want. Then exit. Everything will in Poser will now work as usual again- but with a new, and unique, lightset. 2) Windows XP. Creators work normal in XP, EXCEPT for the fact, that XP allows two scripts to start simultaneously- which neither Python nor Poser allows. So you get the cryptic messages. recap:) When using XP, take care to start ONLY ONE program at the same time. 3) Mac: there is a weakness in the binding in Poser,Mac version, from the mainbuttons.py. The Mac version has therefore a POWERFUL path clause, that will bring everything back to where it should be- but to get there, you have to a) Close mainbuttons.py b) then go to the File menu, select "Run Python script..." and select one of the Creator programs from there. It will restate paths and run as normal. And lastly: dear, dear everybody, Read The Manual. I have taken immense pain and trouble to explain all possibilities and problems there (there are two in total, three if you count XPs weird behaviour). Read it, and create painlessly thereafter ... :-) And the very last point: if you have questions- PLEASE post them to me as well- and post my answer on your question, if youre kind, thereafter on this forum. Im immensely proud of these programs, and it really hurts me you seem to find my beauties so difficult- while all the time, the answers were there for you in the manual- and I would have been happy to help you solve your problem. I only wish somebody had told me of this before! Paul C. Bos webmaster@pcbos.nl
