@ Michael - Thanks for given it some consideration Michael ... It was just an idea. As you say the more heavily bloated and expensive rendering suits do tend to be where the camera matching is, other than Blender, which to be honest i cant use for modelling ... Too cumbersome. I can live without it but it would have been nice to have something like it in a pure modelling package.

Otherwise here's a quick update on how things are going. For rendering purposes those fans in the back-end are good enough, but they are a mish mash of parts that wont marry up so will need to be re-done at some stage.
