Texture Swaps

You do not need Blender or Unreal Engine to change a texture. If you only want to recolour or repaint an existing asset, you can export the texture, edit the image, and repack it - a much lighter path than a full model swap.

Critikal wrote a beginner-friendly guide (and a video) for exactly this, shared in the guides channel and linked in Credits.

The shape of the workflow

1. Find and export the texture with FModel - locate the asset and export its texture.
2. Edit the image in any image editor (recolour, repaint, replace).
3. Bring it back in as the game’s texture asset and pack it into a _P mod .pak - see Packaging & Pak Pipeline.
4. Test in game.

Understanding the texture naming conventions helps you pick the right file (base colour vs normal vs mask maps behave differently).
