Thanks, Ron,

I rendered this in KeyShot. It's not exactly the cheapest render engine out there, but of the ones I have tried, it is by far the easiest and fastest, meaning that the cost can quickly be offset against an easy workflow and an increase in productivity. It does have its quirks, of course, but the developers seem to listen well to feedback and have frequent updates.

A new version 5 is on the horizon, and I think everyone purchasing version 4 now will get a free upgrade to version 5.
