Model viewer help.

[Skyla Doragono]

To be honest if you're not experienced at all with model rendering, it does take some learning for quirks that models have. You're welcome to try and learn though! However most rendering application do require half decent processors and gpus or it takes a VERY long time and is quite slow. In terms of applications, most people use 3DS Max or Cinema4D, but I know some also use Blender which is free.

This is what Dazz suggested for me when I asked the same question. I haven't had the opportunity to try any of these yet, but I do know that Blender is a pretty popular freebie.
