A practical example
Straighten a curved ribbon
Start with
examples/skadira/curved-ribbon.blend: a fictional ribbon of 4 quads bent through 90 degrees, whose UVs follow the curve. All four faces are already selected.
Get this result
Validate reports a valid strip: 4 quads, 5 cross-sections, uniform spacing, rectangle 0.7023 x 0.1000 UV, and nothing changes. Straighten Strip turns the curved UV arc into a straight rectangle of the same size with five evenly spaced cross-sections, inside the 0 to 1 UV square. The mesh does not move. Ctrl+Z brings the curve back.

How it works
Download and extract your bundle
Buy the Skadira bundle at /store/skadira/ and extract skadira-0.1.1-guide-bundle.zip. Keep program/skadira-0.1.0.zip zipped: Blender installs that inner ZIP. Open GUIDE.html for this manual and PRACTICE.txt for the worked exercise.
Install it in Blender
In Blender 4.5 open Edit › Preferences › Add-ons. Click the ▾ menu at the top right of the list, choose Install from Disk…, and select skadira-0.1.0.zip. Make sure Skadira UV Strip Straighten is ticked. To remove it later, use the same list: the add-on's ▾ menu › Uninstall.
Select one strip
Click one mesh object, press Tab for Edit Mode and switch to face select (press 3). Select one continuous strip of quads: no triangles, no branches, not a closed ring. Only one object may be in Edit Mode.
Before you buy
- Blender 4.5 LTS (any 4.5.x). The add-on refuses Blender 4.6 and newer until they are tested.
- A mesh with a UV map. You select one continuous, unbranched strip of quads in Edit Mode.
- Checked on Linux with Blender 4.5.14. Windows and macOS have not been checked yet.
- The purchased skadira-0.1.1-guide-bundle.zip download. It contains program/skadira-0.1.0.zip; the program itself is unchanged from the earlier release.
In Blender 4.5 LTS, install the inner skadira-0.1.0.zip via Edit > Preferences > Get Extensions > Install from Disk; select one open unbranched quad strip in Edit Mode and use the Skadira UV sidebar.
Compatibility & limits
One continuous open quad strip only. No general unwrap, packing, UDIM, branching, multi-object editing or mesh repair. Host GUI checked on Blender 4.5.14 Linux; macOS and Windows unverified.
