We are thrilled to announce Selectable Track Matte Layers for Adobe After Effects 23.0 beta! Any layer in your comp, no matter where it sits in the layer stack, can be used as a Track Matte source for any other layer. You can even have multiple layers all reference a single layer for their matte. You can also use the matte layer’s Alpha or Luma channels and invert them if necessary. Important! Projects saved in the 23.0 beta will not be able to be opened in other versions of After Effects (including the 22.5 public release). If you need compatibility with 22.x or before, please follow the instructions below: Moving from v22.x to v23.0 - On opening a project in the 23.0 beta, you will be presented with a message that the project needs to be converted. Simply click “Ok”, and the project will be updated automatically. The old project will be untouched. “Save as” the project in 23.0 so that you don't need to convert again in the future. Moving from v23.0 to earlier versions of After Effects (i.e. 22.x or below) - Please use the option Save As > Save a copy as v22/v18 to create a project that is compatible with older AE versions.

Hey there! As of today's beta (23.3 build 9) we’ve added several menu commands to allow you to add, modify, or remove Track Mattes on your selected layers.

There are specific menu items to use the layer above or below as any type of Track Mattes, in addition to items for changing or removing the type of a Track Matte layer already selected. And of course, all these commands can have shortcuts applied to them, so your favorite Track Matte setting can be assigned to all your selected layers with one keystroke.

The updated menu commands are located in the Layer > Track Matte submenu and any keyboard shortcuts assigned in a previous version of After Effects will carry over.

Let us know what you think! We’re excited to see how this can help streamline your workflow.

I really wish these track mattes would update their parent link when you copy and paste a group of them. I have a series of boxes that have to come up and each box masks some text inside. I created the main box animation with another layer of text that is masked by the box, then copied and pasted these two multiple times to create the rest of the array in sequence. Unfortunately all the multiple copies keep the original source of the mask, so I have to manually relink all the text layers to their accompanying box. It would also be great if there was a preference to not turn off the masking layer when you apply it. Regardless I super appreciate this feature, just hope this can be worked out in future versions.

How would I pick whip one of my layers to a null to carry over transformations? This was something I would do often. I would track a point in the tracker and apply that to a null then link the layer to the null so I can adjust the layer while maintaining its tracked properties.

Hi Sean,

You can still do that, in fact nothing about that has changed! Use the Parenting column pickwhip to inherit transforms.

The Track Matte column now has similar controls to the Parenting column, but that's only because there's similar "pick a layer, any layer" decisions for you to make.

I found it thank you! for some reason, my parenting column decided to hide so mistook the new track matt whip for the parenting whip lol

Still getting this problem with track mattes and text layers. Fringe still shows color underneath.

When copying and pasting a layer and its track matte to a new comp, can you avoid breaking the reference?

It would also be great if when copying a layer that has an effect that references another layer (like a blur depth matte) and pasting into a different comp, if you also copied the referenced layer, it would paste both and preserve the link.

Thank GOD.

Thanks for this!

There is a bug/oversight I found. When selecting multiple layers to pickwhip or dropdownmenu select which they layer they should track matte to, only the one from your selected position gets applied.

This behavior is not seen with layer parenting. Please have it work the same.

Hi all,

Scripting support is now available for this feature in the AE 23.0 beta as of build 37: https://community.adobe.com/t5/after-effects-beta-discussions/new-scripting-api-for-selectable-track-matte-layers/m-p/13161305/thread-id/2271

Please give it a try and let us know what you think!

This is a very welcome feature!

Regarding the conversion of v22 project versions to v23, it would be really useful to have a means of converting a large number of projects automatically whenever there's a file format change like this.

I run a fully automated template-based rendering system with hundreds of project files so it would save me a lot of time if I could batch-convert all of those project files to the new version automatically rather than having to individually open each file, click 'ok' on the dialogue box and resave the project file.
