I'm considering Poser 5, but I have recently purchased and am planning to purchase a lot of the character textures that currently work with P4. Will these still work for me if I upgrade? I've invested quite a bit in them, and since I'm almost done acquiring all the models and textures I need for a movie project, I'd hate to have to start all over if I bought Poser 5. Thanks to anyone who can answer this! --silver
