Today, I’ve taken a short break from making Corona even more awesome ;). Someone at the forum pointed out, that the great and powerful (and free) Bercon maps are not available for new 3ds max versions. Since the author decided to opensource them, I was able to compile a 3ds max 2015 version.
You can download it here http://corona-renderer.com/stuff/BerconMaps2015.zip. It is of course still free. If you don’t have Corona installed, you might need to download the x64 MSVC 2013 redistributables to make them work. If I have the time, I’ll update them again for the future 3dsmax versions.
