Uv Squares

Blender's UV Editor tool that reshapes UV selection into grid.

Installation

Go to Edit > Preferences > Addons > Install and select .zip file (do not unzip!)

UV Editor > N Panel > UV Squares

Reshape selected UV faces (quads) to grid of either:
- equivalent squares (each square area is the same)
- or by respect to shape of an active quad (area of rectangles can differ but they fit into straight lines)
convert multiple islands at once (select more than one separate UV chunk)
Align sequenced vertices on an axis (X or Y axis is determined by slope automatically):
- make them equally distanced
Rip faces (deselect vertices from unselected faces, as if there were seams)
Join selected vertices to any closest unselected vertices
Select single vertex and snap 2d cursor to it

Aligning to axis

All vertices have to be ordered/sequenced by x/y value depending of X/Y axis that they are getting aligned to. Otherwise you will have swapped vertices in the result.
What script does here:
- set pivot to cursor (sets it back after)
- 2d cursor will snap to closest vertex and the alignment will be made at that verts x/y value, depending on the axis
- restrict scale to axis (recognize X or Y by the slope)
- scale to 0 to where the cursor has snapped

Reshaping to grid

Works on any UV selection shape of quad faces
You can specify an active quad by making it the last selected face. If not, one face will automatically be taken
2d cursor is snapped to closest corner and is determining the direction for calculating the length of start and end of grid as well as length of one unit for square grid

Rip faces

Join vertices

Snaps selected vertices to closest non selected
- For faces, if you want to connect islands back to their original place - use stitch (shortcut: V, while stitching press I to toggle island)
