I didn't understand anything, but there's another method:
Create an object for the map.
In the object, create not a new model, but a new effect.
In the effect, create a ModelInstance file.
In this file, select the wall model in the 'model' line.
Next, you need to find the scale line - it indicates 1, change it to 2 - that's it, the object is ready, it's large and rotates.
I knew that scaling effects works well, but I didn't know that you could add static models to the effect. The method looks interesting. I'll try it, thank you.
