Wow that was fast. I think I understood what you mean. If it really is like that, then I would like to find out why those are called Pri/Sec Axis instead of Forward/Right Vector.
Btw doesn’t it work same as “Set…Frame” node’s “Ref Frame Rotation”?
I’ll give it a try tomorrow as I’m extremely tired right now. Hopefully I can use that node… finally. Thank you for letting know
