How to find a rotation of another coord system ?

Lets say we have a global coord system and local coord system and that local coord system is rotated by some amount by some arbitrary vector.
How could I find this rotation vector and angle given the two coord systems ?

localRotation or localEuelrAngles

check if Transform.InverseTransformPoint could help you. but its hard to tell what to do when we have no information about your setup.

I think it had to do something with inverse.

I thought that there would be no replys to this post so i have posted another similar one “How to find vector coords in some other coord system ?”.

Better to bump after time, not create an identical topic, with different wording. Helps in future Google searches.

Oh, sorry. I hope now someone respond there, I don’t know how to delete it, if its even possible.

You just edit and say it was solve, even post a link here.

Yea, here is the link.
