Rendering?

I'll preface this with I'm pretty much new to this whole game of 3d drawing. I picked up MoI after playing with the demo and finding out just how easy it was to use. I see a lot of cool stuff people have created on here, and it seems people take their MoI models and then import them into a rendering program to put cool paint jobs on them (I know that's a fairly simplistic term).

So my question is, now that I've learned to use MoI, and become fairly proficient in it - what's the logical next step? I'd like to take a stab at putting together some rendered drawings of the space ship I just completed, but frankly I know nothing about rendering or the tools used. Anyone have any recommendations on where I should start?

I know this is a pretty open ended question, but I'm really enjoying my journey into the world of 3d modeling and want to try and take that next step.

Thanks.
