HI Abdullah @Julaybeeb ,
That’s a good question🤔
Although this Course is to show you what specific Modifers do and how to use them, not so much when to use them, I’d also would like to know use cases of the Mask Modifier.
In well over 12 years, I have never used it (or have it seen being used) and actually forgot that it existed😉, but I’m sure that it has its uses.
