ok this is my new free Studio setup and in this all light is only shader (illumination HDR) and you can control the spot with expresso look the preview.
is work on all version of cinema4d but the gi setting is for c4dR11.5 so if u have 11 or less just adjust the GI setting.
so is free for all for personal or commercial use but not for release. if you add this to your blog or website just send me link and credit.
