I'm playing with this great Z-flatten python script by Ockham (you can find it on Renderosity, it's an upload of 4 or 5 days ago) and I think it's great to improve cartoonish style ! i think you know Laura the model ( >CIAF!< ... ehm... Posy says hello to all... ), so I'll show you: In the first picture you can see Laura in a "normal" render, in the second picture there is laura after using the Z-flatten Phyton script and rendering. I use Poser 4 pro and phyton scripts are in the package, but I know there is an utility somewhere that can be used if one doesn't have phyton script package included in Poser. In the second picture I moved a little the camera and pose because Laura's pose have become a little strange after flattening and stretched the rendered picture horizzontally just a little. I want to test it with an anime-style (have you red the great tutorial by SnowSultan at Renderosity ? It is in the "tutorial" section...).
Testing the script I found that you don't have to parent figures (conforming is ok, just not parented) because it creates two balls and all figures goes automatically parented to these two balls and a mess could happen...
Hope this is useful to you...
(... Meanwhile Laura and Posy are reading Guiltypleasures' "Savannah and the harley ride" and they are chatting in a low voice... I hope Posy will not have strange ideas.... Sigh!...)
