We take a look at an alternative to Unity's default UI for a better editing experience.
Unity’s default preview window is limited: UI elements can’t be previewed correctly, particles don’t play, sprites face the wrong angle, lighting is flat, and switching clips resets the camera every time.
VoxelLabs’
Ultimate Preview Window is an editor extension designed to solve these workflow issues by replacing the standard preview with a more complete and readable preview environment.
Ultimate Preview upgrades Unity’s built-in preview window, letting you inspect UI elements, sprites, animation clips, VFX Graph systems, particle effects, and 3D models with clearer lighting and full camera controls. It automatically plays animations, rotates sprites to face the camera, and gives developers a more consistent visual reference when switching between assets.
You can think of it as a general-purpose improved preview inspector for most Unity assets, built to remove the common pain points of the default Unity previewer.
The tool integrates directly into Unity’s Inspector. When selecting an asset, Ultimate Preview automatically replaces the standard preview behavior with its own enhanced preview pipeline.
- For assets like animations, it plays the selected clip automatically and preserves the camera position between selections, making it easier to analyze motion and shapes.
- For sprites and UI elements, it aligns the asset toward the camera and applies cleaner lighting.
- For Particle Systems and VFX Graph effects, it loads a contained preview environment with playback tools and scene-like lighting options.
All preview settings can be adjusted from a small toolbar: camera presets, lighting intensity, background color, skybox, floor settings, and more.
- Custom Preview Window – UI Toolkit: A small editor extension that allows you to build custom preview windows for UI elements using Unity’s UI Toolkit (supports previewing UI assets, customizing view layout).
Differences: This tool is lighter and focused primarily on UI preview via UI Toolkit rather than full VFX/animation/3D asset preview. If you mostly preview UI elements, it may suffice; but Ultimate Preview gives broader coverage (particles, models, animations).
- Ultimate Preview Window – Community Edition: A free version from the same publisher (VoxelLabs) that offers core preview enhancements (UI, sprites, camera control) but with fewer features and likely less support than the Pro version.
Differences: Community Edition gives you a cost-free entry but lacks the full feature set, performance optimizations or support of the Pro version. If the budget is tight and your needs are modest, it’s a viable alternative; but for full productivity and broader asset types, the Pro version gives more.
