Ministry OF Flat UnWrapConsole3.exe Documentation for version 3.7.2

It only takes .obj files, but most tools can import and export obj-files, so it should work for most usages.

UI Version

To change the camera, press the right mouse button. Right + Left dollys, and Right + Middle pans. Multi-touch camera controls also work (two fingers to tumble/zoom and three to pan), as well as standard Maya camera controls by pressing Alt + mouse buttons.

Click in empty space to switch between 3D and UV view.

Contact and Feedback

If you encounter any issues, please mail me, and if possible, send me the mesh you have problems with. If you can’t send the mesh, a screenshot will also do. If you are having problems, you can turn on the “validate” option in the settings. This will run a bunch of validation steps and output any errors it finds in the betray_stdout.txt file. It only gets better if I know what’s wrong with it!

UV mapping is subjective, so if you have opinions, please let me know. If you think it sucks, LET ME KNOW and tell me why.

Note: I am more focused on hand-made meshes with good topology than on scanned meshes, so that will remain my focus for now.

Follow me on Twitter at @quelsolaar. I will post when I release new versions and when issues are fixed.

Overlap Identical Parts

  • Description: Overlap identical parts to take up the same texture space.
  • Command-line usage: -OVERLAP <TRUE/FALSE>

Debugging Settings

Warning:
All following settings are for debugging purposes only.
Making any change to these settings is likely to result in worse UV mapping and/or longer processing time.
