Earns its place in the superhive library as a focused fix for a specific, well-known quirk: the zero-area UV islands the Screw modifier leaves on faces parallel to the ground.
The Screw modifier in Blender is known to produce poor UVs by using cylindrical projection. That projection does not reflect the real face area of skewed faces, and UV islands for faces parallel to the ground tend to have a zero area. Screw Modifier UV Fix, from Styriam sp. z o.o., targets this problem.
To use it, apply the Screw modifier, then right click in edit mode and choose Fix Screw Modifier's UV from the context menu. The new UV is scaled proportionally to the lengths of edges in the main edge loop. The addon is meant to be used only on meshes generated by applying the Screw modifier, and if you run into problems, check that all normals face the right direction.
The addon lists compatibility with Blender 3.0 through 5.0 and is released under the GPL license. Documentation is included.
Screw Modifier Uv Fix is best for blender users cleaning up UVs on meshes created by applying the Screw modifier.
Screw Modifier Uv Fix is completely free to download and use.
Screw Modifier UV Fix lists compatibility with Blender versions 3.0 through 5.0. If you are running a Blender release in that range, the addon should be available to you. It is released under the GPL license. Because Blender's addon API can change between major releases, it is worth confirming behaviour on your exact version and checking the developer's page for the latest details on supported builds before relying on it in a project.
Screw Modifier UV Fix works from Blender's edit mode. First apply the Screw modifier to your mesh, then right click to open the context menu and choose Fix Screw Modifier's UV. The addon generates a new UV that is scaled proportionally to the lengths of edges in the main edge loop, which addresses the zero-area islands left by the modifier's cylindrical projection. If the result looks wrong, make sure all normals face the right direction, as the addon recommends checking normals when problems occur.
Screw Modifier UV Fix is meant to be used only on meshes generated by applying the Screw modifier, so it is not a general-purpose UV repair tool. Run it after applying the modifier, and it will rework the UVs that the cylindrical projection produced. For meshes made another way, this addon is not the intended tool. If you encounter problems on a valid mesh, the first thing to check is that all normals are facing the right direction, which is the addon's recommended troubleshooting step.
Screw Modifier UV Fix is listed as free here and is released under the GPL license. Licensing terms can change over time, so for current pricing and license details it is best to check the developer's page directly. The GPL license generally governs how the addon's code can be used and redistributed. If you plan to rely on it in commercial work, reviewing the license and the developer's page will confirm exactly what the terms allow for your situation.
