Hi Ralf, thanks for the message, yes 3.3.15 is the latest release but it has nothing added to it to be of any value to me to install it. If it aint broke don't fix it applies to me. Plus it's not my copy (yet), and I need more time than Luxion allow to test things because i actually spend the vast majority of my day having to take care of my disabled wife. Sadly most companies don't take these circumstances into account, and that does sadly include MoI, but a 200 quid gamble with MoI and it's excellent support from its users and from Michael is far safer than a 2000 pound gamble with Luxion when they cant even answer a question about how come they can interpret IGES NURBS, but not MoI/Rhino ones. So for now Keyshot is experimental to me at this time and is likely to stay that way until i can afford the gamble or until my friend wants his back.
