LightRoom update - Mask modification - unable to apply a mask

[PeteCoch]

Hello, quick question LightRoom Classic 11.01, when i create a mask on a photo, i'm unable to apply it on my picture (when i quit the modification area, the mask is not taken into account). Is it a parameters or something to unlock or....?

Are you confusing the mask overlay with mask edits?

[PeteCoch]

Hello, thanks for your reply, to be accurate, I start the modification usin' the mask button (pencil etc...),  I realise all of my stuff, saved my mask details but nothing happen on the original picture while i quit the mask edit. So I might 'confusing something for sure!

Maybe this will provide some guidance-

And, as is the 'nature' of Lightroom,- Original files are not altered- ever! Editing changes will be applied to any derivative file when you 'Export' the image you have editied.

Some screenshots would help. Walk us thru what you are doing, with screenshots.

Thank you for your help, let me first try with your protocole (link), it seems to exactly describe my mystake. I guess i've the habit to have my developpment directly impacted and not only preset. That's why. Thank you for your patience.
