Okay. It works now. Thank you so much.
I noticed one more oddity. Probably it’s not related to current parenting problem, but I started to see it on last release. If you will open browser console during my previous playground: https://playground.babylonjs.com/#4517EG#14 you will see two warnings:
Cannot read properties of undefined (reading 'rotationQuaternion')
Looks like they are caused by cloning walls:
let wall_4 = wall_1.clone("wall_4");
and
let wall_5 = wall_1.clone("wall_5");
It’s interesting, that those warnings are caused only by those two walls above.
const wall_2 = wall_1.clone("wall_2"); doesn’t lead to warning.
Why is this happening? Is it a problem? Can it be avoided?
