Find UV Problems Before Texturing

UV Stretch Monitor helps you quickly detect UV distortion, locate problematic areas, and see exactly where they appear on the 3D model - without manually inspecting the entire UV layout or relying only on checker textures.

Color Bar - Find Problematic UVs Instantly

No need to manually search through the entire UV layout.
The interactive Color Bar shows the distribution of UV distortion across the entire layout. Click or drag any range to instantly select the affected faces or UV islands.

3D Problem Zones - See UV Problems Directly on the Model

Enable 3D Problem Zones to visualize problematic UV areas directly on the model. UV and 3D selections stay synchronized, so you can immediately locate the affected geometry.

Analysis Modes - Multiple UV Analysis Modes

UV Stretch Monitor includes several analysis modes for different UV problems:

• Distortion - detect relative UV compression and stretching.
• Absolute Stretch - analyze directional UV stretching.
• Texel Density - identify inconsistent texture density.
• Island Size - compare UV island scale and distribution.

Simple Workflow

1. Analyze
Choose an analysis mode.

2. Check the Color Bar
See whether problematic values are present.

3. Select
Click or drag the problematic range.

4. Locate
Enable 3D Problem Zones to see the same areas on the model.

5. Fix
Correct the UVs and recalculate.
