I know that most (almost all) Poser scripts at RDNA have been updated for 9/Pro 2012. I think there’s a full list of those updated scripts somewhere in the RDNA forums. That’s all that I know of since those are the only python scripts I regularly use. I hadn’t noticed any scripts that didn’t work in both 9 and Pro 2012 since they use the same python which is different from 8 and older. (The more I read that last sentence, the less sense it seems to make. lol)
Oh, I remember that the DAZ products Crying Time and Hybrid Grunge Bundle have been updated for the latest Poser as I have both and they use python to apply the shaders.
What do you mean by “texture filter script”? What is such a script supposed to do? I might be able to help if I know what you mean.
