Using the new polygon margin settings
my name is Masaya and I'm a designer working at Live2D. Today I wan't to introduce a few new psd import features introduced with the Cubism Editor 2.1.06. Several issues with psd importing are fixed in this version, too, so please give it a try. The new version allows you to set "inner" and "outer" polygon margins in the psd import dialog. They allow more precise and better automatic generation of polygons from psd layers. (Please excuse that the screenshots show the Japanese editor).
Boundary margin (Outside)
This value controls the outer offset of the polygons to the outer edge of opaque image elements.
Boundary margin (Inner)
This value controls the inner offset of the polygons to the outer edge of opaque image elements.
When you import a psd for the first time, all layout and polygon settings will have their default value. Although these are recommended values, adjust them to your needs. You can always reset the values to their defaults from "Edit" -> "Reset polygon settings".
