Matrix Constraint

This script allows you to apply matrix constraints and perform other functions, such as setting the influence of how much the parent object controls the child and using the offset parent matrix to freeze transformations.

Why matrix constraint?

Matrix constraints perform better in complex scenes since they use matrix multiplication, which is computationally more efficient than handling individual constraints. This can reduce evaluation overhead, leading to faster playback in complex rigs.
