Texture Sheet Splitter

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.

---

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

When not to use it

• 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

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 & 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.
