This is the same as the previous post, but with a larger canvas.

To change the dimensions, edit this line, near the top:

scale = 750 # Scale the UVs and the display area

This improves the polygon updating and changes the normals handling.  It also adds a menu bar, with save and close as options, as well as options to activate "blind scrolling", which will speed up the scrollbar handling if a large mesh is loaded - although you'll end up scrolling blindly, as it were.  I haven't come up with a better solution for that yet....

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
