Masks No Longer Work on a Repeatedly Used Project

[Andy.Diesel91]

Hi, all
My name is Andy Diesel. I have been working on this project for a long time, but my masks have recently stopped working.

This simple motion graphics project depends on sequentially adjusting the masks' opacity to reveal their contents.
The masked layer has no effects; every mask is 'Add'ed in. As seen in my reference, I'd removed one to test further, but there was still no change.

I can only expect that I mistakenly pushed the wrong quick key since my other sequences of the same kind are still working. While I scroll through this project, there is no sign of why they're no longer working.

I am using the 13" Macbook Pro M1 2020 with 8Gig RAM.
I use Adobe Creative Cloud.
(I did recently downgrade my After Effects to the 2023 version due to too high a demand on my internal memory)

If you have any questions, please ask. I would greatly appreciate the external input.

Hi Andy,

Thanks for writing in. By looking at the screenshot, I don't find any reason why the opacity animation is not working. What happens if you remove the keys and change the opacity? Does it work? Please share a screen recording so that we can understand it better. Or feel free to DM me the project file so I can take a look.

Note: Moving this thread from Bugs to Discussions for troubleshooting.

Thanks,

Nishu

Hi and thank you for your response, Nishu_Kush.

I've attached a recording of what the timeline looks like and how it differs with other working timelines.
I've further duplicated those working timelines and pasted the layers from the troubled timeline in without fixing the problem.

Hope this can help and I will try compile everything to share the project with you and send a link.

Hi, Nishu_Kush

I found my issue was that I'd mistakenly drawn a large mask over my entire layer and made all other masks invalid.

I do appreciate your response though.
