Documentation & Help
Installation
- Download the UV King .zip file
- In Blender, go to Edit > Preferences > Add-ons
- Click Install, select the zip file, and enable the addon
UV King will appear in the N-panel of the UV Editor.
Basic Packing
- Select your mesh and enter Edit Mode
- Open the UV Editor and select all UV islands (
Akey) - In the N-panel, find UV King
- Click 'Pack'
Adjust the margin and rotation settings as needed.
UDIM Workflow
- Enable UDIM mode in the UV King panel
- Assign islands to specific UDIM tiles using the tile selector
- Pack!
UV King will pack islands within their assigned tiles while maintaining optimal density.
Using Heuristic Search
Enable 'Heuristic Search' for maximum density results. This mode tests multiple packing configurations to find the optimal layout.
Note: This takes longer but produces the best results.

Frequently Asked Questions
?Which Blender versions are supported?
UV King is optimized for Blender 4.0 and above, including 4.1, 4.2 LTS, and 4.3+. For best performance, we recommend using the latest Blender version.
?How does UV King compare to Blender's built-in packing?
UV King offers significantly faster packing, higher density results, UDIM support, stacking capabilities, and advanced group workflows that are not available in Blender's built-in UV packing.
?Can UV King handle large projects with thousands of islands?
Yes! UV King's high-performance engine is specifically designed to handle thousands of UV islands efficiently without slowdowns.
?What is heuristic search mode?
Heuristic search mode tries multiple packing configurations to find the optimal layout with maximum density. It takes longer but produces the best possible results.
?Does UV King support UDIM workflows?
Yes, UV King has full UDIM support. You can assign islands to specific UDIM tiles and pack them independently while maintaining optimal density.
?Is there a trial version?
We offer a 14-day money-back guarantee. Try UV King risk-free and get a full refund if it doesn't meet your needs.
?How do I get updates?
Updates are provided through Blender Market, BlenderKit, or Gumroad depending on where you purchased. You'll receive email notifications for new versions.
