ZUV Tools

ZUV Tools is a great addon to flesh out your Blender UV tools. Bringing over features from modeling and some extra features ZUV Tools allows you to manipulate your UV's easier than ever.

2.0 Information

1.0 is now the free version of ZUV Tools. For an up to date version please go to blender market for 2.0! 2.0 has many bug fixes (especially when selecting loops that begin and end on the same seem); Smooth, shortest Path, and Auto Weld now work in sync mode; added Relax; Shortest Path now will select the UV closest to the mouse cursor (so you can click and ctrl+click just like in the 3D View); Ratio now auto-selects the entire island for you; Auto Weld uses distance and 2D cursor for UVs that can connect to multiple other UVs; Shortest Path is now faster; icons, icons everywhere; plus when you run an operator the settings appear in the bottom left pop-up menu so you can change the settings and it'll redo the operator with those settings!

1.1.2 - Fixed an issue that prevented the addon from working on non-Windows platforms

1.0 Features:

Shortest Path

With two selected UVs this operator will find the shortest path according to the selected algorithm and source. I suggest assigning a mouse click hotkey to it. I use CTRL + Left Click

• UVs - Derive distance from UV coordinates
• Mesh - Derive distance from 3D vertex coordinates

Algorithm

• Simple - Fastest. Attempts to find the shortest path by searching through connected UVs/vertices and finding the one that is closest to the end. (Speed > Accuracy)
• Distance - Uses the A-star algorithm in order to find the shortest path
• Topology - Uses Djikstra's algorithm to find the shortest path via the number of edges instead of distance. (Slow due to needing to search through most if not every UV)

Spread

Straightens selected UVs according to type. When assigning a hotkey I would suggest something your nonmouse hand can easily select and ALT. This is helpful when selecting loops (Alt + Click) and spreading. I use Alt+T.

• Linear - Spreads UVs out with equal distance from one another
• Cubic - Spreads UVs out with relative distance according to their distances on the mesh

Smooth

Smooth selected UVs. Great for when interior UVs of the same island are intersecting and Minimize Stretch isn't doing what you want.

Circle

Turns selected UVs into a circle

Transfer Selection

Transfers selected UVs between UV sync modes

Auto Weld

Similar to Stitch (hotkey 'V') but simpler and will only move individual UVs instead of entire islands

UV Merge by Distance

Similar to Merge Vertices by Distance or Remove Doubles this operator moves any UVs within the set distance to the same location (does not weld unless Blender automatically welds them)

Reunwrap

Attempts to reunwrap selected UVs. It also tries to scale and move to where it was before reunwrapping.

Copy Paste UVs

Easily copy and paste UVs from one uv map to another (based upon vertex order so usually is only possible on the same object)

Scale to Bounds

Scale selected UVs to fit boundaries (does not keep original dimensions of selected UVs)

Correct Ratio

This operator attempts at scaling the selected UV island in order to relatively match the mesh dimensions. UV Island X length / Y Length : Mesh corresponding to UV Island's X Length / Y Length
