Problem scaling parent without scaling child

Hi there,

I'm having some problem with the following code:

Son.parent = null; Father.localScale *= 1.5f; Son.parent = Father;

I have a Father->Son structure and O intend to scale the father without changing the Son's size.

If I try the code above everything goes has planned and the Father is scaled without affecting the Son. However if I do this:

Son.parent = null; Father.localScale *= 1.006f; Son.parent = Father;

the Son is scaled instead of the Father...which is kind of weird.

Any ideas of why this is happening? Thanks.
