As I mentioned - I have an architect friend that is interested in learning TC, so I've been brushing up a bit lately with v18 to serve as an instructor/taskmaster. As for getting away from TC - I still use it for designing personal things but my employment is no longer in a field involving 3D work. Could be a good reason for you three to meet up :-) Well first of all, Darrel - I would love to meet Henry and David in person, for no other reason than that I have enormous respect and fondness for them both. Rendering and lighting is the hardest part to master and there is very little info on this. I know Henry has already done one on materials and much of it is still relevent. What took you away from TC then? You know what would be great if you, Henry, David could write a book on materials and rendering in TC.
