• Search across your entire palette
• Favorites for materials you use constantly
• Auto-tracks scene selection (toggleable)

What it isn't

• Not a shader tool — works with any material regardless of shader

Includes

• MatSwap editor window (dockable)
• Group asset type with custom inspector
• Documentation and example scene

MatSwap: assign materials in one click, without dragging from the Project window.

Keep the materials you're working with in a palette, organized into groups like Bricks, Foliage or Metals. Select an object and its material slots appear. Click a material to assign it, or shift-click to arm several slots and fill them in one pass. Track Selection follows your Hierarchy, so you can work through a whole scene without stopping.

Features

• Grouped, searchable material palette with favorites
• Multi-object selection, mixed slots and sub-meshes
• Full undo and correct prefab overrides
• Works in URP, HDRP and Built-in
• Editor-only: no runtime overhead, no asset bloat

If you've ever dragged the same material onto fifty objects in a row, this tool is for you.
