lol i am really trying not to complain about the things that are not working properly within R3. Because in the end ZBrush is just such an exceptional piece of software, that i really try to overlook the bad parts.
My question is just: do they really have to invent EVERYTHING from scratch. I mean sometimes it is definitely better too “steal” something well done, than to create something from scratch that in the end was not worth the effort. (First rule of advertising) 
Anyways in the case of Lightbox it really took me some time to understand how it works and now i love it, with the only exception that you can’t navigate through your entire computer. It just stops at the program files folder.
