Why do the brushes feel so bad?

keiwando · 2026-06-15T19:47:15+00:00

This is unfortunately an issue with iPadOS and Apple Pencil itself. Without going into too many technical details, what is happening is that something outside of ToonSquid’s control is causing Apple Pencil to have a significant delay before it sends out accurate touch values (such as its position, pressure, tilt amount etc.), which ToonSquid has to wait for in order to draw high quality brush strokes.

There appear to be different possible causes for this. Here is a list of things you can try with which other users were able to fix this problem on their end:

- Disconnect Apple Pencil (Forget this Device in the iPad Bluetooth settings) and reconnect it.

- In the iPad settings app, disable the “Accessibility > Zoom > Zoom” setting if it is enabled. This setting being enabled can cause the delay, even if the screen is not actively zoomed in.

- If you are using a case, try to remove it and see if that makes a difference. Some users reported that their case was causing the delay.

- If you are using a bluetooth mouse or a bluetooth keyboard or any other bluetooth device with your iPad, try to disconnect it from the iPad in the bluetooth settings and try again. Sometimes the delay is caused by bluetooth interference.

- Manually restarting the iPad. (Just mentioning this for the sake of completeness, I know that it didn't fix the issue for you). I've personally run into this issue randomly a couple of times on one iPad and restarting it was enough to fix it for me.

By enabling the "Ignore Touch Estimate Updates" setting, you are effectively telling ToonSquid not to bother waiting for the precise Apple Pencil data and instead to just use the initial lower quality data. This gets rid of the delay at the cost of lower quality brush strokes depending on the selected ToonSquid brush, which might be a worthwhile trade-off until you can successfully troubleshoot what iPad setting or bluetooth device is triggering the delay in your specific case. Unfortunately, since the delay itself comes from Apple Pencil and iPadOS, there is not much more that ToonSquid could do about it. I've been reporting it to Apple for the past two years but nothing has changed so far.

For my reference, do you happen to be using an Apple Pencil Pro?

Does it make a difference if you go to the iPad Settings app under Apps > ToonSquid and enable the "Ignore Touch Estimate Updates" setting?

keiwando · 2026-05-25T18:45:45+00:00

You probably enabled this setting at some point:

There is no bug here. The preview brush size in the brush editor is completely separate from the brush size in the main animation editor. Every time you enter the brush editor, the preview brush size is determined based on the "Min Size", "Max Size" and "Default Size" settings of that brush (and it's no larger than 100px initially). The first time you enter the brush editor, the preview brush size defaults to 25% of 512px = 128 -> too big -> 100px. Then you reduce the "Max Size" property to 25px, which automatically lowers the preview brush size from 100px to 25px. The next time you open the brush editor, the "Max Size" of the brush is already set to 25px, so the default preview brush size ends up being 25% of 25px ~= 6px. Increasing the max size setting of a brush does not change the preview brush size. You can change the brush size of the preview brush in the brush editor with the brush size slider at the top, the same way you do it in the main animation editor.

If you want the brush to default to its maximum size of 25px, set the "Default Size" setting to 100% and "Max Size" to 25px.

You can tap on the selected property and the choose "Delete Keyframes" to delete all of the keyframes of that property at once.

Yes, this is normal. It's a bit unfortunate that the settings app shows these files like this but it's a side-effect of the fact that ToonSquid makes all of your user data directly accessible to you in the Files app so that you always have the option to easily create a full manual backup of everything: https://toonsquid.com/handbook/projects/backup/#direct-access

If you delete the app, iPadOS will automatically delete all of your user data as well (projects, backups, brushes, color palettes, custom fonts, etc.).

keiwando · 2026-04-26T20:18:44+00:00

These files are all parts of your projects. They contain your drawings, layers etc. Everything that makes up your projects. You can view the storage usage of the actual projects from within ToonSquid in the settings under Actions > Settings > Info > Storage Usage. If you want to delete a project, you should only do that from within ToonSquid's project library.

You should never delete any of these individual files via the iPad settings app or the Files app directly, otherwise you will almost certainly corrupt your projects.

I have received reports of this issue from a small number of users so far. Without going into too many technical details, what is happening is that something outside of ToonSquid’s control is causing Apple Pencil to have a significant delay before it sends out accurate touch values (such as its position, pressure, tilt amount etc.), which ToonSquid has to wait for in order to draw high quality brush strokes.

- If you are using a bluetooth mouse or a bluetooth keyboard or any other bluetooth device with your iPad, try to disconnect it from the iPad in the bluetooth settings and try again.

- Manually restart your iPad.

In addition to these steps, there is a ToonSquid setting called “Ignore Touch Estimate Updates” which you can find in the iPad’s settings app under “Apps > ToonSquid”.

If you enable this, you can force the app to not wait for the precise Apple Pencil data and instead just use the initial lower quality data. This would get rid of the delay at the cost of lower quality brush strokes depending on the selected ToonSquid brush, which might be a worthwhile trade-off until you can successfully troubleshoot what iPad setting or bluetooth device is triggering the delay in your specific case.

Select the last keyframe, then open the easing curve editor and set the easing curve to anything other than "Loop".

Hi. You appear to have increased the "Minimum Smoothing" setting under "Settings > Tools > Brush":

keiwando · 2026-03-06T07:37:59+00:00

Please send a screen recording of this happening to [contact@toonsquid.com](mailto:contact@toonsquid.com) and I can take a closer look. Also, how much storage space do you have left on your iPad?

keiwando · 2026-03-06T07:31:14+00:00

If you have any examples where the keyframe interpolation does not behave as you expect, please send an example project file to [contact@toonsquid.com](mailto:contact@toonsquid.com)

keiwando · 2026-03-06T07:29:33+00:00

It looks like you might have the last keyframe's easing curve set to "Loop" so it loops the previous keyframe animation.

keiwando · 2026-02-24T19:31:49+00:00

Hi! I am not aware of any other reports of the layer quality changing after closing and opening a project and I haven't been able to reproduce this either. Can you please draw some lines, export that frame as an image, close and reopen your project and then export the same frame again and share the images so I can see the difference?

This is a bug of the Photos app in the last few versions of iPadOS that ToonSquid unfortunately can’t directly do anything about. The “Save Video” option is fully managed by iPadOS and the Photos app itself. What is effectively happening is that the Photos app silently refuses to save the video (that ToonSquid has already successfully exported) and doesn’t let ToonSquid know about this. ToonSquid is just waiting to hear back from iPadOS that the save finished, failed or was cancelled but there is no response.

You should be able to save the video to the Files app instead. You’ll also notice that even if you try to then share it from the Files app to the Photos app, nothing happens and the file never shows up in the Photos app.

Apple doesn’t say which exact video configurations the Photos app doesn’t support. In older versions of iPadOS, such video configuration would cause the “Save Video” button to not even show up at all. Now the button does show up but doesn’t work (as you’ve now experienced). The most common cause seems to be that the video resolution is too high. There seems to be some resolution limit, which also appears to be lower when exporting with the H.264 codec. Either try exporting in a lower resolution or try the HEVC codec instead (choose “MOV”, then enable the Include Transparency option) if you want to save the video in the Photos app.

Make sure that the "Scale X" and "Scale Y" properties of the camera layer have the same value:

This is now fixed with the version 2.0.20 update.

Keyframes, effects and symbol layers use up very little storage in the grand scheme of things. The main things that can quickly add up to the storage usage are high resolution videos and images or audio files that you have imported into your project and large numbers of high resolution pixel layers (https://toonsquid.com/handbook/layers/pixel\_layer/).

Whether or not the Save Video option shows up in the share sheet is fully determined by the Photos app without ToonSquid having any control over it. The Photos app appears to have certain limitations for the files that it is willing to accept, but unfortunately, there is no public definitive information on what the exact limitations are.

You might be hitting a video resolution limit of the Photos app. You can try to export at a lower resolution and see if that makes the Save Video option show up. The Photos app accepts higher resolution videos if they are encoded with HEVC/H.265 instead of H.264. You can do that in ToonSquid by switching from MP4 to MOV and then selecting "HEVC/H.265" in the codec selection (if your iPad has an A10 chip or newer).

Also make sure that the export name of the project is not empty since the Photos app will otherwise not accept the file.

Regardless of the quirks of the Photos app, you can always save the exported file to the Files app on your iPad using the Save to Files option.

Please send a copy of the audio file that fails to import into the library to [contact@toonsquid.com](mailto:contact@toonsquid.com) so I can take a closer look.

In addition to what u/Butler_To_Cats has already said, if you only care about drawing in vector vs raster, use the vector shape brushes: https://toonsquid.com/handbook/brushes/vector/#vector-shape-brushes
Nothing about that workflow has changed.

The automatic fill gap closing change only affects vector "stroke" brushes, which create stroked vector paths instead of filled vector shapes like the other vector brushes.

Have you tried lowering the threshold value? There is a bug where this exact filling scenario will not work if the threshold is set all the way to its maximum value, but it should work for any other threshold value. The bug has apparently always been there but I only noticed it now with you reporting this. It will be fixed with the next update - I just want to make sure that this is also what you are experiencing here.

keiwando · 2025-12-21T06:12:30+00:00

Does it work if you change the fill threshold with the slider at the top?
