🚀 What It Fixes and Improves

Automatic Thumbnail Generation

Automatically generates thumbnails for 3D Models, Sprites, Particle Systems, and UI elements as soon as they’re imported or modified.

Adds Missing thumbnails:

Automatically Adds proper thumbnail support for Particle Systems, UI elements, and Sprites, replacing Unity’s empty or misaligned previews.

Poorly lit and unclear default icons:

Unity’s default thumbnails often appear dark or generic. Ultimate Thumbnails fixes this with customizable lighting, camera angles, and background options.

GUID-based and fully reliable:

Thumbnails are linked using asset GUIDs which means you can freely move or rename your assets without breaking their thumbnails, everything stays perfectly in sync.

No thumbnail customization in Unity:

Unity doesn’t let you control thumbnail lighting, camera, or resolution—Ultimate Thumbnails adds this capability

Sprites and UI always face the camera:

No more weird-angled 2D thumbnails—Ultimate Thumbnails automatically aligns sprites and UI for perfect visibility.

Enhanced list and grid view icons:

View your generated thumbnails in both Grid View and List View modes directly inside the Project window.

Quick generation and cleanup:

Easily generate, clear, or refresh icons for individual or multiple assets with right-click context menu actions.
