There is a bug in corona, making Materials invisble on certain render elements, which [screwed me over](https://forum.corona-renderer.com/index.php/topic,6614.msg44811.html#msg44811). It happens by corona unchecking “Visible in mask” Checkbox, when jumping between the daily builds and the official build.  
I was promised a script that would check that back automatically, for my scene with 200+ materials. Since there is no such script in the Goodies section, I found it via google custom search in the resolved bugs forum, originally [submitted by mirokurcik]([https://forum.corona-renderer.com/](https://forum.corona-renderer.com/) [Masks based on materials will behave different between Daily Builds and Alpha](https://forums.chaos.com/t/129828) ). So I reuploaded here, should there be a soul of similar fate searching for an answer.

tl:dr  
Script checks “Visible in Masks” checkbox for every material in the scene.
