Make a long tube fluorescent lamp (I should have qualified that in my earlier comment).

You must try rendering some C5Pro scenes that use "advanced" features like raytraced soft shadows (then try this with Vue). Compare rendering complex, high res Vue scenes with GI and RT soft shadows -- compared to C5Pro -- I've done all this. Have you used the terrain modeler -- used the various terrain filters, used the surface replicator to place objects using a distribution shader? You can convert replicated C5Pro objects to "real instances,"(though I don't know why one would want to export them?).

Give yourself a lot of time with C5Pro! I have used both to a large extent, and I honestly think that C5Pro has far more features to learn than Vue, and is a much better overall value -- unless, you simply import stock objects and render small resolution (my small is about 3000x1900). I spent ~$600 on V5I, and...I could write a book on it...problems, objectively defined!

I assure you, C5Pro is an excellent program, but I do confess that you can certainly get up and running faster with Vue5I, but there is a price to pay for a simpler program.

I will say this, Carrara has a rendering engine that has made high-end 3D application users smile when using it!
