Basic Usage (Quick Start)

1. Select your object

2. Enter Edit Mode

3. Open the UV Editor

4. Select all UV islands (A key)

5. Open UV King panel

6. Click Pack

Your UVs will be automatically arranged for better space usage.

Auto Unwrap

Use the built-in presets to quickly unwrap your mesh:

• Smart UV (66°) → balanced for most models

• Auto Seams (45°) → better for hard-surface objects

• Lightmap (89°) → more cuts, less overlap

• Cube Projection → simple box-style mapping

Packing Settings

• Margin → space between UV islands and borders

• Padding → space between islands

• Scale Option

  • ON → allows resizing for better packing

  • OFF → keeps original scale (important for texel density)

Stacking

Use stacking to place identical UV islands on top of each other.

• Saves texture space

• Useful for repeated objects (chairs, bolts, panels)

Groups

• Create groups to organize UV islands

• Pack groups separately or together

• Lock groups to keep their position

Quick Tools

• Rotate UVs (±90°, ±45°)

• Normalize → equal texel density

• Orient 3D → match UV direction with 3D model

• Copy / Paste UV → transfer UVs between similar meshes
