In several of my pages I mention a site named Renderosity.
It is not only a great place to acquire assets (many low-cost or even free), but it’s a gathering place for digital artists of all kinds.
Their extensive forums bring together users of the Blender, DAZ and Poser software packages discussed here, as well as users of just about every other digital creation software out there. They even have a forum called “Freestuff”.
You can check Renderosity’s forums out here.
