Normalize Object Space. The tool transforms the object space matrix (or desired components of it) to identity state. The geometric points are transformed with the inversion matrix so that their positions in the world space remains unchanged.
This tool is useful when one needs to animate transformed objects. Scaling and skewing is often introduced as a result of a normal modeling work flow. However, in animations, objects are easier to manage if their object spaces are world oriented.
The tool can be applied selectively to any of the following single transformation components:
