Please see here: https://coronarenderer.freshdesk.com/support/solutions/articles/12000066916-how-to-use-masks-with-reflection-refraction

In order to utilize propagation of masks, you will need to have Corona v.6 DB installed, you can find the latest daily build here (18/06/2020): Dropbox - Error - Simplify your life

I am afraid we do not understand your question correctly, because you never correctly described what exactly you would like to achieve. Can you please clarify? I don’t think “I need reflection refraction mask” + a link to your portfolio is good enough. Can you please give us a bit more detail what exactly you are looking for? Maybe an example how it works in V-Ray?

raw reflection = CShading_RawComponent set to “Reflect”
reflection filter = CSading_SourceColor set to “Reflect”
reflection = CShading_Reflect

It is the same with refraction. Hope that helps!
