What's wrong with C's renderer? Overall I'd have to say I think I often like what I see coming out of C better than what I see coming out of Lightwave (and even though I own both products I still feel like I can probably get something nicer looking out of C). Maybe it's just a personal taste thing but to me Lightwave renders can tend to seem cold/flat/muddy/lifeless relative to what I see coming out of C (or C4D for that matter). Or are you referring to the lack of features like caustics, radiosity, and HDRI?
