Why we like it

Boundary Fill earns its place in the aescripts library for one focused job: decorating text layer boundaries with effects applied directly to the text, while staying compatible with text animators. Version 2.2.0 supports After Effects 2025, 2024, and 2023, and it's listed as free here.

What is Boundary Fill?

Boundary Fill is an After Effects plugin for decorating the boundaries of text layers. Effects apply directly to the text layers themselves, and the tool is compatible with text animators for easy control.

It includes Dynamic Opacity, which makes the fill opacity proportional to the opacity of pixels within the boundary, and Dynamic Size, which makes the fill size proportional to the boundary size. Scale By Saved Ratio scales the texture to 100% size based on the saved size from Text Save. Position changes the text position according to the texture's position, while Opacity adjusts the text opacity according to the texture's opacity. Overlap Distance prevents lines from being generated around the boundary, and Overlap Smoothness softens the Overlap Distance by adjusting the opacity.

Version 2.2.0 was released on June 19, 2025, and runs on After Effects 2025, 2024, and 2023. It's part of the aescripts library, and a demo video is available.

Frequently asked questions

What After Effects versions does Boundary Fill support?

Boundary Fill runs on After Effects 2025, 2024, and 2023. The current version is 2.2.0, released on June 19, 2025. If you're working across several machines or plan to change your After Effects install, check that your version falls within that range before installing, since compatibility outside those releases isn't stated. For the latest details and any newer builds, the developer's page on aescripts is the place to confirm what's supported.

Does Boundary Fill work with text animators?

Boundary Fill is compatible with text animators, which the developer notes makes control easier. Effects apply directly to the text layers, so you decorate the boundaries of your text as part of the same setup. If you already build type with After Effects text animators, the plugin is meant to fit that workflow. A demo video is available if you'd like to see it before installing, and the developer's page carries the full details.

Is Boundary Fill free to use?

Boundary Fill is listed as free here. Licensing terms can change over time, though, so for the current arrangement and any conditions attached, check the developer's page on aescripts. Downloading from the official source also ensures you get version 2.2.0 or whatever the latest build happens to be, along with any documentation the developer provides. That's the most reliable way to confirm pricing before you commit to installing it.

What do the Dynamic Opacity and Dynamic Size options do?

Boundary Fill includes a Dynamic Opacity setting that makes the fill opacity proportional to the opacity of pixels within the boundary, and a Dynamic Size setting that makes the fill size proportional to the boundary size. Alongside these, Scale By Saved Ratio scales the texture to 100% size based on the size saved from Text Save. Overlap Distance prevents lines from being generated around the boundary, and Overlap Smoothness softens that by adjusting the opacity. Together these give you control over how the fill responds to the text.
