Lightwave3D is also probably the most unusable and user friendly to a beginner - especially the fact they have 2 programs, one for modeling the other for animation and rendering.
Top5 Render engines at the moment are
1. Pixar Renderman/Pixal (Softimage/Maya)
2. Messiah:Render (Softimage/Maya/Max/Lightwave)
3. trueSpace6.5 "Native" (trueSpace)
4. Splutterfish Brazil 1.1 (Max/Maya)
5. Mental Ray 3.3 (Softimage/Maya/Max/Lightwave/trueSpace)
although Lightwaves is good in its standard state, it doesn't even compare to the others any more ... a few years ago it was the best but they've not updated many of it features since 6.0 (makes it very old and decrepid by todays standards)
trueSpace is true value for your buck $299 for 6.5 if you download the demo first (which is also the smallest around at 13Mb) with that you get Poser4 technology for animation and such. Although Poser was never a good modeler its animation and humanoid features were quite outstanding for the begginer
if you want something with alround abilities you'll want Max4 ($500 from Discreet themselves) + a beta copy of Brazil 0.4.8 ... although it does watermark the images, you can go back and give it that film look by painting the watermarked area's black.
however for true power and rendering i'd go for Softimage or Maya, which you can pickup Maya 4.5 Complete w/Mental Ray for $1,200
alternatively you can download Softimage XSI EXP 3.0 (which is technically XSI 3.0 almost entirely) for free.
Only rub is no commercial purposes - however really the way i see it you can develop them now in it, then when you need it for commercial purposes get your publisher to foot the bull for a full copy
might seem weird but that does actually get around the legalities of the matter.
that aside for a min, i'm not sure i follow on what you mean - post a screenshot up of what your game looks like ... i'll see what i can suggest
