jntdigital, thanks for your imput. The work flow from ADT to Vue could be an issue. Let me ask you. If the model was built with materials all added and ready to render. Then the clinet/ boss makes changes to the building and/ or site do you have to reload the new model and start from scratch with Vue or do you just reload the new model and the materials reassign to the previous layers?
Yes, VIZ is still a stripped down version of 3ds MAX. VIZ does not have the movement nodes and some other features.
lambros, thanks for your imput. We do all our modeling in ADT 2006 and when has a model been built that has not required changes.

I am using some of the options you mentioned in your post such as RPCs and Bionatics. I have also started learning to use Mental Ray which is a rendering option in VIZ 2006. As for Vray and Maxell I know the firm is not going to go that route any time soon. The firms focus, main objective is to make the building or interior space the main focus of the rendering/ animation.
