Export Batch

Node icon
Export

Exports all palette variants as individually named files, completing the variant generation pipeline.

Export Batch takes a Variants input (from Palette Remap or similar) and writes every variant as a separate file. Each file is named using the base name plus the variant’s palette slot name. For example, a base name of “gem” with a palette slot “crimson” produces “gem_crimson.png”.

This is the node that makes ArcBrush’s batch workflow possible: one graph produces dozens of consistently named output files automatically.

The output directory supports relative paths: type export and it resolves relative to your .arcb file. Directories are created automatically.

Parameters

Section titled “Parameters”

Export

BrowseText

Output directory for exported files

Base NameText
Default: export Range: 256 chars

Filename prefix; variant name appended

FormatChoice
Default: PNG

File format

  • PNGLossless with transparency. The default choice for game assets and sprites.
  • JPEGLossy compression, small files. Good for web assets without transparency.
  • TGATarga format. Common in game engines like Unity and Unreal.
  • BMPUncompressed bitmap. Maximum compatibility, large files.
  • WebPModern format, smaller files than PNG/JPEG.
  • TIFFProfessional archival format with multiple compression options.

*Format Settings*

Quality %Integer
Default: 90 Range: 1–100

Compression quality for JPEG/lossy WebP

MatteColor (RGB)
Default: rgb(255, 255, 255)

JPEG matte color behind transparent pixels

CompressionInteger
Default: 8 Range: 0–9

PNG compression level; 0=fastest, 9=smallest file

RLE CompressionToggle
Default: true

Run-length encoding to reduce TGA file size

LosslessToggle
Default: false

Lossless WebP; no quality loss but larger files

CompressionChoice
Default: None

TIFF algorithm

  • NoneNo compression — fastest but largest files.
  • LZWLossless compression — good balance of size and speed.
  • DeflateLossless compression — smaller files than LZW but slower.
  • PackBitsSimple RLE compression — fast but less effective on complex images.

Export

Generate Sprite SheetToggle
Default: false

Export a sprite sheet PNG + JSON manifest instead of individual files

Sheet Layout

ColumnsInteger
Default: 4 Range: 1–32

Grid columns. Auto-set on enable; Auto Fit button resets to roughly square

Padding pxInteger
Default: 0 Range: 0–32

Space between cells in pixels

BackgroundColor (RGBA)
Default: rgba(0, 0, 0, 0)

Sheet background color

Power of TwoToggle
Default: false

Expand sheet to next power-of-two dimensions

Notes

Same per-format options as Export Image (see above). Quality is shown for JPEG or lossy WebP.

Sheet Layout controls are only visible when Generate Sprite Sheet is enabled.

Usage Tips

Section titled “Usage Tips”
  • Set a descriptive base name, since it becomes the filename prefix for all variants.
  • Use relative paths (e.g., export or output/sprites) to keep exports portable alongside your .arcb file.
  • Enable Sprite Sheet to also generate a packed sprite sheet PNG with a JSON manifest.
  • All format-specific options (quality, compression, etc.) apply to every exported file.
  • Use Ctrl+Shift+E to quick-export, or File > Export All (Ctrl+Shift+Alt+E) to run every export node in the graph at once.
