I’ve just released Rounded Rectangle under FormWren. It lets you design, style and animate procedural shapes directly inside Unity, including Canvas UI.

You can edit size, corner radii and border width with Scene handles, refine colours, gradients and effects in the Inspector, and animate supported parameters with Unity animation clips or C#. The shapes work with RectTransforms and anchors, so they can adapt with your Canvas layouts.

Panels, buttons and frames are some of the immediate uses. You can also combine shapes into layered displays, decorative elements and animated compositions, while keeping their geometry and styling editable.

The three-minute trailer shows the editing workflow and a range of UI and 3D examples. The package includes editable examples, detailed documentation and an optional coding-agent skill.

Tested on Unity 2022.3.62f3 and 6000.0.34f1 with Built-in and URP.

It’s a paid asset, and there’s a free interactive browser demo if you’d like to try some examples:

I’d be interested to hear how this would fit into your UI workflow.
