Being new to this I have done the usual "visit every site known to man" thing. Of  all the sites I have visited Renderosity is the best all-around in terms of functionality and content. There is also a lack of the elitist attitude found elsewhere in regards to the tools used to create art. This site may be geared toward Poser but there is no lack of support for other formats. Having such an open venue for art, without regard to the method used to arrive at the result, creates an environment conducive to growth and expansion of vision by all involved.
The hard work to make this site exemplary is noted and appreciated. Too often only complaints are voiced, so I attempt to offer congratulations and thanks where deserved instead.
