Ok, well first you'll have to mention what other modeling/rendering apps you are using. There's several kinds of plugins for several different apps, ranging from "high end" to "mid range". BodyStudio by Reiss Studio is the main one for hosting PZ3 scene files in 3dsmax v5 to v7, Maya, and C4D. Vue, Carrara, and Shade all have their own plugins for this. I think Vue5i has it standard. I don't know of any available for Lightwave or XSI however.
