well. if you plan to use it with bryce for rendering then no its not as all the advancements will not work in bryce IE, dynamic hair, the fierfly render and texture room. You will be able to use the face and cloth rooms. so only you can deside if thows will make it worth the price for you. I am one that has have relativly few problems with P5 right out of the box. and personaly love the program. But then it is a time saver for me as till now i had to export to Maya then do my hair and cloth then export to the porgs i used to render in Bryce 5 is one of them. Now with the firefly render engin i render most of my work in poser set up cloth and dynamic hair in poser. So for me it was a worth while investment. Laters Vel
