Excellent tool, that takes away the need to switch selection method. Only tool missing currently is a 'fill' command, where the selected UVs are scaled to fill the whole UV space, quite useful for decals.
Thank you :) I'm not sure if it will give the exact result you're expecting, but Align Operations > "Normalize" might offer similar functionality.
It works, even on the Mac. Still a lot to do.
Problems
Nice to have
Overall a huge benefit. Lets hope it get improved. Would pay for it.
I tried to support multiple UVs but Blender does not support this. Only one of the UV Maps will be used. In .max files also boxmapping and 2d mapping (similar to greasepencil) is stored in 3 dimensional UVW maps, blender only supports two vectors (U, V) thats why only the supported UV map will be imported.
Why is the Extension version 2.2.2 But the Gumroad download: 2.4.1
