Ok, you guys got me beat for sure. I couldn't get Poser to render the dynamic hair in a reasonable amount of time, regardless if it was casting shadows or not. This first render (above) was my first attempt. Rendered at 720x480, 3 lights, all of them casting depth mapped shadows. Took Poser6 5 minutes just to calculate the scene shadows and set up the render, then took about a minute or two to render after that. So this render took a total of about 6 minutes, and I don't think the hair looks that realistic.
