Texture Sheet Splitter

Module: Art · Category: TextureArt · Tool ID: TextureSheetSplitter

The inverse of Flipbook Maker: take an existing atlas or sprite sheet and split it into individual UTexture2D assets. Supports uniform grid splitting with configurable rows, columns, padding, and margin. Live cell-size preview before commit.

Tool open with a 4×4 sprite sheet loaded, cell preview visible, output prefix and folder configured.

When to use it

• Importing a third-party sprite sheet and needing individual frames as separate textures
• Recovering individual textures from an atlas built without the source files
• Converting a VFX flipbook back into per-frame textures for re-edit

What it isn’t for

• Don’t use this on packed atlases with non-uniform cell sizes. Only uniform grids are supported. For irregular packs, you’ll need to extract regions manually.

Opening the tool

1. Open the EQLabs Hub and search for Splitter (or browse to Art → TextureArt).
2. Click the tool card.
3. Drop a Texture2D into the Source field.

Section	What it does	Default
Source Texture picker	The atlas / sheet to split	(empty)
Rows	Vertical cell count	4
Columns	Horizontal cell count	4
Padding X / Y	Pixels of padding inside each cell	0
Margin X / Y	Pixels of margin around the entire grid	0
Output Prefix	Filename prefix for split tiles	Tile
Output Folder	Where to save the new textures	(empty = same folder as source)
Copy Source Compression	Apply the source texture’s compression to the split tiles	true
Source dimensions	Read-only display of source texture size	—
Cell Width / Height	Computed cell size based on rows/columns/padding/margin	—
Update Preview	Recompute the cell layout
Split & Export	Performs the split and saves all tiles

Tool with cell preview showing computed cell sizes overlaid on the source, output settings configured.

Workflow

Step 1: Drop the source texture

Pick the atlas / sprite sheet from the Content Browser via the picker.

Step 2: Configure the grid

Set rows and columns to match the source. The Cell Width / Height fields update live as you change values.

Step 3: Tweak padding/margin if the source has gaps

Padding is inside each cell (gap around each individual sprite). Margin is around the whole grid (gap at the edges of the atlas).

Step 4: Set output

Pick an output folder and prefix. Tiles are named <Prefix>_R<row>C<col> by default.

Step 5: Click Split & Export

Each tile is created as a UTexture2D asset and saved to the output folder. Compression matches the source if Copy Source Compression is on.

Settings reference

Field	Range	Default
Rows	1 – any	4
Columns	1 – any	4
Padding X / Y	0 – any	0
Margin X / Y	0 – any	0
Output Prefix	text	Tile
Copy Source Compression	bool	true

Settings are persisted to [Project]/Saved/EQLabs/Settings/TextureSheetSplitter.json.

Output

• New UTexture2D assets. One per cell, saved to the output folder.
• Naming convention. <Prefix>_R<row>C<col> (zero-padded for sortable ordering).
• No source modification. Source texture is untouched.

Tips and gotchas

• Cell size = (SourceWidth - 2 × MarginX - (Columns - 1) × PaddingX) / Columns. If you get fractional pixel results, your padding/margin values don’t divide cleanly into the source dimensions.
• Copy Source Compression preserves quality. Turning it off forces default compression on the split tiles, which can degrade non-default-compressed sources.
• Output folder defaults to source folder. Leave empty to save tiles next to the source atlas.
