Rounded Rectangle: Procedural Shape System for UI & 3D

Create resolution-independent UI and 3D shapes in Unity. Edit with intuitive gizmos, style with gradients and effects, and animate with Unity animation clips or code. No textures required.

Geometry and editing

• Resolution-independent procedural shapes.
• World Mesh, Canvas Mesh UI and Canvas SDF rendering paths.
• Circular, Squircle and Bevel corner profiles.
• Adjustable width, height, border width and independent corner radii.
• Custom Scene gizmos and numeric Inspector controls.
• Fill and border slider controls.
• Unity UI RectTransform and anchor integration.

Surfaces and effects

• Fill and border colours, gradients and optional textures.
• Border colour profiles and spatial gradients.
• Independent fill and border transparency.
• Automatic opaque/transparent material selection for World Mesh shapes.
• Canvas SDF outer glow, inner glow, drop shadow, inner shadow and emboss.
• Unity UI masking and clipping workflows.
• World Mesh integration with Unity scene depth and occlusion, with configurable draw-order modes.
• Available effects and rendering behaviour depend on the rendering path.

Runtime and workflow

• Animation through Unity animation clips or the public C# API.
• Button, layout, grid and animation helpers.
• Runtime shape handles.
• Optional generated World Mesh colliders that update with shape changes.
• Render caching.
• PNG and single-layer PSD export for individual Canvas SDF shapes.
• Flattened PNG export for supported Canvas selections.
• Editable example scenes and included HTML documentation.
• Optional agent skills and instructions; no AI service is required.

Compatibility

• Tested Editor versions: Unity 2022.3.62f3 and Unity 6000.0.34f1.
• Built-in Render Pipeline and URP.
• Included optional URP/XR supplement for pipeline-specific World Mesh shaders and materials.
• Unity UI (com.unity.ugui) required.
• HDRP is not supported.
• Tested native targets: Windows, macOS, Android, iPhone, iPad and standalone Meta Quest 3.
• WebGL demo available.
• Quest 3 setup uses URP and OpenXR; input and interaction use your project's XR systems.
• Transparent sorting follows Unity renderer rules.
• Performance depends on rendering path, active effects, screen coverage and target hardware.

Sketch, explore and refine designs without leaving Unity.

Rounded Rectangle is a procedural shape system for creating panels, buttons, frames, HUDs and layered 3D interfaces. Adjust geometry and styling on the same editable object, without preparing a new sprite for every variation.

Direct editing, from silhouette to surface

Use custom Scene gizmos to resize shapes, adjust borders and edit shared or independent corner radii. Refine values in the Inspector and explore Circular, Squircle and Bevel profiles.

Familiar Unity UI workflows

Work with RectTransforms and anchors so your shapes adapt with your Canvas layouts. Combine them with standard Unity UI content, masking and clipping to create resolution-independent interfaces for different screen proportions.

Explore different visual styles

Create flat interfaces, softly inset controls, embossed surfaces or glowing sci-fi panels. Combine fill and border colours, gradients, independent transparency and rendering-path-specific effects. Textures are optional.

Animate and add depth

Animate layouts, styles and effects with Unity animation clips, or drive them through the C# API. Build layered World Mesh compositions that interact with Unity scene depth and occlusion. Enable generated MeshColliders for physical interaction as shapes change.

World Mesh shapes automatically select opaque or transparent materials when using automatic material management.

Editable examples and documentation

Explore the included scenes, Inspector tools, button and layout helpers, and detailed documentation. Optional agent skills and instructions support AI-assisted authoring workflows without requiring an AI service.

The trailer and gallery show designs created with the asset. Included example scenes are listed in the documentation; not every promotional composition is supplied as a ready-made scene. Gameplay, inventory and economy systems depicted by sample interfaces are not included.
