Thanks Danny, I don't mind tweaking and playing with the guts of OS's - I have been around computers for a long time (Yawn), things might be native to an OS but you generally find you still need to tweak things here and there to get the best from them. But I do expect an artistic tool to be quick and easy to learn. Rhino was like that, but it just feels as if it's loosing its way. Alias is like way too expensive and the learning curve isn't even a curve if you know what I mean. I was trying out MOI but sadly my partner suffered a severe brain injury and I never got to finish my trial period, however the little time I got to play impressed me quiet a lot, a single person development showing a consistent logic to the tools and just being able to play and find things was fun but intuitive.

Thanks for the render engine - I scoured the net last night and found several multi-platform ones so I am going to try some over the next few days and see how they work out.

Many thanks to you all
