Precise UV Export

Precise UV Export is an add-on for Blender 3.0.0 or above. It lets you export a pixel-perfect UV layout of a mesh to an image. Convenient for making low-resolution textures, where the default UV export is not ideal.

How to install:

1. Download the latest release or clone this repository.
2. Install precise_uv_export.py in Blender's preferences.
3. Enable the add-on.

How to export:

1. Open the UV Editor view.
2. Open the UV drop-down menu.
3. Press Export Precise Layout.

Export settings:

• Image Size - specify the width and height of the exported image.
• Shade Islands - fill each island with a different shade of grey.
• Grid Overlay - overlay a checkerboard pattern on the exported image.
• Outline Islands - draw an outline around every separate island.
