I would definitely recommend the update as it is one that I have not questioned. Esp. if it is on sale.

It has an entire new pbr render engine (don't wory firefly is still there) based on cycles. I had to plug it even though I have never used it and don't think I ever will as I do NPR rendering.

The really big thing for me and I do not see many others mention is the improved comic book rendering and Geometric line edge. I believe they collaborated with artist Brian Haberlin to bring these improvements which is really impressive. For this type of art poser 11 is hands down the best tool to use and creates the best line art. And it is fun.

I admittedly do not use any of the stock content. Except maybe for a background character once in a while.

...now if they were to improve the already good animation tools....hint ...hint
