well if producing what i am looking for would be better( and more easily) achieved by exporting my models to another app....what app should i use?

Well, my vote would go to anything that has Mental Ray as a render engine... Maya, 3ds Max, Softimage...
If you have Poser Pro, it comes with hosting plugins for Maya, Max, Lightwave and Cinema 4D, which aren't very good in that all it exports is Poser stuff with simple Phong shading and textures, but at least the texture channels are already plugged in and you can expand on the surfacing from there.
But those are all high level apps and not really for beginners. In your first post you sounded like you had something in mind already.
All those programs have a fairly steep learning curve, especially the Mental Ray part of it, but they also all have fully functional 30 day demos to try out. I don't know about Cinema 4D though.
You could also look into Vue, as I think it comes in cheaper versions without all the bells and whistles, and Softimage has a completely free version called Mod Tool, which is made mostly for game modders and people who want to learn the program without the time limit of the demo.
