Well, I think I will have to figure out a better way to render my models. If I use POV-Ray, I should only model pieces in Rhino and put it all together in POV-Ray procedurally. However, I don't think that is very productive and I would rather produce an entire structure as one model that can be imported into different applications. I have access to Lightwave but I don't know how to use it. Thus, I will probably try to complete the modeling of the other four orders of columns and try to learn a few skills in Lightwave for now. I hope to be able to build the houses and temples in Palladio's books someday...
