Complementary weight

This tool allows you to easily adjust the weight values of the joint areas where two bones are connected.

When adjusting weight values for joints, it's common to switch between two bones to fine-tune the values. Often, these two values have a complementary relationship.

By creating a "complementary weight" modifier, modifying the weights of bone A simultaneously adjusts the weights of bone B. The two values maintain the relationship WB = 1 - WA.
