.uasset Preview & Diff

Unreal Engine asset files (.uasset) are stored in binary format. Standard text editors and version control tools cannot display their contents. Textil analyzes the internal structure of assets and provides preview and diff capabilities.

Textil extracts the following information from asset files:

• Export Structure: Objects within the asset (root, components, CDO, etc.)
• Property Values: Values held by each object’s properties
• Import References: Dependencies on other assets

.uasset Preview

The preview feature lets you examine the contents of a single .uasset file. This is useful when you want to quickly check an asset’s structure or property values without launching Unreal Editor.

Property Tree View

Displays the asset’s property structure hierarchically.

• Shows properties in a tree structure for each Export object
• Expand arrays and nested structs for inspection
• Filter properties by name or value using the search feature

Graph View

For node-based assets like Blueprints and Materials, you can view the node structure in Graph View.

• Visualizes nodes and connections
• Switch between multiple graphs (EventGraph, ConstructionScript, etc.) using tabs for Blueprints
• Zoom and pan to examine details

Supported Asset Types

Asset Type	Display Content
Blueprint	Node graphs for EventGraph, ConstructionScript, etc.
Material	Shader graph node structure
Material Instance	Parameter override values
Texture	Texture settings, MIP levels, and other metadata
DataTable	Data in row/column format
Level	Actor list and properties

For asset types not listed above, you can still view contents using the Property Tree View.

.uasset Diff

The diff feature lets you compare changes between two versions. Where traditional version control only shows “binary file changed” for .uasset files, you can now see exactly which properties changed and how.

Property Tree View

Displays the property structure hierarchically with changes highlighted.

• Added properties: Highlighted in green
• Deleted properties: Highlighted in red
• Modified properties: Highlighted in yellow, showing before and after values side by side

Changed nodes are automatically expanded, while unchanged nodes remain collapsed. Enable the “Show changes only” filter to hide unchanged properties.

Graph View

For node-based assets like Blueprints and Materials, you can view changes in Graph View.

• Side-by-side or top-bottom split view to compare before and after
• Changed nodes and edges are highlighted

Diff Level Filter

In Graph View, you can filter by change significance:

Level	Changes Shown
Logic	Only logic-affecting changes (node additions/deletions, connection changes, pin configuration changes)
Layout	Logic + position and size changes
Visual	All changes (including visual changes like colors)

The default is Logic level, hiding cosmetic changes that don’t affect logic.

Change Navigation

The diff view provides navigation features for efficiently reviewing changes:

• Previous change / Next change buttons to move through changes sequentially
• Current change position is highlighted
• Auto-scrolls to change location

Diff Context

Diff view is available in the following contexts:

Context	Comparison
Staged	HEAD vs staged changes
Unstaged	Staged (or HEAD) vs working tree
Worktree	HEAD vs entire working tree
Commit	Comparison with a specified commit

The appropriate context is automatically selected based on the status shown in the file list.
