transform.InverseTransformPoint not working correctly in 2019.3.1f1

Not sure if this is a bug, or if I’m just being stupid but, according to the docs:

transform.position is the world space position of the transform. (example: -3.5, 1.7, 2.0)
transform.localPosition is the local position of the transform. (example: 0.0, 1.7, 0.0)
transform.InverseTransformPoint Transforms position from world space to local space.

So then, how come transform.InverseTransformPoint(transform.position) == (0.0, 0.0, 0.0) instead of (0.0, 1.7, 0.0)?

How come transforming my world position to my local position gives me a different value?

Is this a bug? What’s going on here?

Figured it out – transform.InverseTransformPoint does not transform to localspace, it transforms to localspace as a child. – e.g. where 0,0,0 is the same position as the parent. – so if you want localspace, you have to use transform.parent.InverseTransformPoint.
