Have you seen what a nice blurry rendering one can do in Carrara Studio 3? Look what FWTempest posted 1 September in the Carrara Gallery... I think that there must be more workarounds for thinks like motion blur and soft clouds. And would you start a renderfarm with Carrara? It is a shame that there was no sound editing and better motion paths in Carrara already as in the likes as Truespace and Animation Master.
