Default Skeleton Color (Transparency)

Creo2 M080

I’d like to change the default skeleton model color, or more accurately, the transparency. The default blue is OK, but making it 75% transparent seems to help in working with it.

I’ve found the option “skeleton_model_default_color” but as documented it only seems to be able to change the color, not the transparency.

Any way to change the skeleton model’s transparency?
