First V4 is so old I'm actually ashamed that poser stile bothers to support her.

Second if you already have a version of Poser than it IS free, just don't bother upgrading to any newer versions.

Third if you are so sure that the that the other programs you mentioned as being "free" are so much better then why are you still trying to work in Poser? AND complaining about it when you can just change programs?

And Finally if you are so disappointed by Renderosity as a whole, why are you even still here?

Have a great Day
