Since last year I've always planned to start animating using Krita and I watched videos on how to use it especially how to animate with it. There was a specific feature there that was important to use, yes the onion skin, and I followed the guidelines of a video on YouTube and it worked perfectly fine and a month ago I finally got my digital tablet and was excited to finally start animating but when I tried using the onion skin, it won't work. I tried everything I could, I re-downloaded Krita and I'm still having the same issue and it's really frustrating. I figured since it's a new version from last year, the process would be different, so now I'm here. I need help, please tell me what to do.

The process/method of setting up and using onion skins has not changed since last year.
Which version were you using last year and which version are you using now?
Which digital drawing tablet do you have? Is it just a drawing tablet or is it a display tablet?

If you've installed the latest version on the same computer then it should look and feel and behave exactly as it did with the older version.

Can you post a full screenshot of the krita window with a simple animation opened and with the Timeline docker, Layers docker and the Onion Skins docker showing?

Firstly, thank you for replying. I am not sure of the version I used last year and I'm currently using the version 4.2.9.
I am using a Gaomon M10K drawing tablet
I have been using the same computer from last year.
I'm not sure how to submit a screenshot so..my apologies.

The easiest way to share a screenshot is to post it to Imgur (or similar image/file sharing site) and then post the link in a reply here. Or you can use any personal Dropbox (or Google Drive etc) service that you have and post the link here.

Does this help?

That link is a 'Google sharing' link and needs sign-in with a Google account. It's intended for 'co-working' types of files.

You need to make a 'Share with anyone' link, which is one of the options when you make a link to a file from your Google Drive. That will enable anyone to download it without needing a Google account.

Did this work?

Yes, that gave a direct download.

Your Onion Skins docker shows the central '0' column as black. That is the overall enable/disable and overall opacity control for all onion skins on all layers.

It's supposed to go black when you slide it all the way down but that's also supposed to turn off the other onion skins when you do that but they're showing as blue, not grey to indicate turned off.

Try clicking in the middle of the black area under frame '0' and that should set it to about 50% opacity.
You can slide it up and down to get any overall opacity you like. It's usual to have the -1 and 1 columns set to 100% and the -2 and 2 set to a lower opacity, about 70% or whatever, and so on the further from the centre that you go. That way you can tell the difference between the different onions skins if you have quite a few turned on.

Thank you so much! I really appreciate this!
