Could you please add support for the Thin Film layer like in the VRay, I recently needed to use it and I regretted that it is still not in Corona. And it would be great to add a mappable Thin Film Amount value for extra flexibility.
Good news, adding a Thin Film section to the Corona Physical Material is already developed, and will be released in Corona 13 (there was no time to test it to include it in Corona 12 Update 2). Keep an eye out for a daily build that will include it sometime soon :)
Released in Corona 13, Friday June 13th, 2025.
Thin film is already available in v13 daily builds.
