There are so many repetitive content in F104: Light & Render! When I unzip part 1, i.e., iClone_6_Fundamentals_F104_Light_Render1, this is what I got (as shown in the picture below): it shows there're 83 files in total, but after I play them one by one, most of them are repetitive, they're just duplicates. These courses are very useful, please check this issue and fix it.
