I wrote a Lightwave plugin (9.6 minimum) that let's you grid a rectangular UV selection of quads (only works on quads). Works on points, edges and polygons (even though you can't select edges in the UV pane). The polygon one is likely the best one to use since it avoid ambiguity in your selection (ie. one polygon uv strips that are separated via discontinuous UV's). Oh, did I mention it works with discontinuous UV's? Even if the UV's wrap around onto itself.
This plugin basically takes the four corners of your selection and grids the points inside to be either A) evenly distributed or B) use the average distance between rows/columns.
There are 4 options:
1. Rectangular (makes the selection rectangular)
2. Axis aligned (aligns selection to X or Y axis)
3. Evenly distribute long axis.
4. Evenly distribute short axis.
Long and short axis go by the number of quads in the selection, not the actual length.
This plugin can really clean up your UV's rather quickly. One trick is to move the corners where you want, select #3 and #4 and click Ok. You'll get evenly gridded UV's inside those corner points.
Note that it tries to check for a uniform rectangular selection, but it isn't 100% robust. If you have discontinuous UV's inside your selection and the UV's aren't EXACTLY at the same position, some UV's won't be moved correctly. This is the first version, so save your work before using it. Let me know if you encounter any issues and if you're using this. I'd like to get some feedback if this is a useful plugin.
