So I want to set values, like scale, of a packedscene from the editor from another scene.
I want “Candlestick” to set the scale of “Top” which is within “Body Hollow” (see below).

The problem is when I run “Body Hollow” scene everything works perfect. But, when I run “Candlestick” it just doesn’t work. I have tried using $Node instead of Signals it grabs the “Body Hollow” node, but then I get a null error on calling body_hollow.scale_x (ofcourse I slighty change the code).
The point is it acts as if “Top” does not exist!

I am trying to find an answer to such a simple problem and yet I can not.

Please help me find a solution. I am going crazy!
Thank you in advance!
