Beyond the fundamental and introductory videos on Luxion-Keyshot site there are few and far online tutorials on features of Keyshot. Lynda.com and Linked_in have also very basic offerings on the subject. Are there any online systematic " learning courses " that cover the intermediate and advanced features of keyshot that you know and recommend ?
I would definitely recommend jumping on youtube and going though the webinars on KeyShot's channel. For some indepth tutorials on specific topics check out Will Gibbons, Esben Oxholm and Liam Martin - they all have great tutorial videos which have helped me learn from scratch. Good luck!
