Normal Tome

Normal Tome: A simple tool to slice and reorder normal map channels.

Normal Tome is a lightweight channel-repacker for normal maps.

If you’ve ever struggled with Blender node setups or confusing channel layouts, this tool will save you time — and sanity.

Load a PNG → choose how each channel (R, G, B, A) maps → save a clean, repacked PNG.

No Blender.

No scripting.

No guesswork.

• []RunNormalTome.exe

  []Click “Load PNG”

  []Choose your channel mappings from the dropdown menus

  []Click “Save Repacked PNG”

  []Convert the PNG to DDS (not addressed here)

  Why It Exists

  Some games use non-standard normal map channel orders (such as putting Red into Alpha), like Baldur's Gate 3.

  Blender can handle this, but the node setup is frustrating and requires using versions that do not support important plugins.

  Normal Tome solves this with a clean GUI and zero setup.
