Rounded Rectangle: Procedural Shape System for UI & 3D

Create one procedural rounded rectangle, shape it directly, then keep it as a world mesh or move it into Canvas mesh UI or Canvas SDF.

What you can build

Build Resizable UI Surfaces And 3D Panels

Create panels, buttons, badges, frames, and world-space surfaces without baking a new texture for every size. Size, radius, individual corners, border, fill, gradients, textures, and supported effects remain editable in Unity.

Start with one generated shape, keep it in 3D, or move it to Canvas Mesh UI or Canvas SDF.

Create your first shape → Compare the rendering paths

First safe action

Create One Visible Shape

  1. Choose Tools > Rounded Rectangle > Create > Rounded Rectangle.
  2. Select the new object and make one visible Scene-handle or Inspector edit.
  3. Confirm that the rounded mesh updates before choosing another rendering path.
Expected result: one visible rounded mesh in the Scene view. If it is invisible or pink, use Compatibility or Troubleshooting before changing several settings.

Shared controls

Edit The Core Shape

Use Scene handles for direct size, radius, independent-corner, and border-width edits. Use the Inspector for exact values, profiles, colours, gradients, textures, and effects.

Scene handles edit size, radius, independent corners, and border width; use the Inspector for exact values and gradients.
