Fake Interior: Errors and Corrections

I’m applying fake interior to the glass windows in the building through a tutorial, but I don’t know this part.

Spawn Actor Collision is acting different then the referenced BluePrint Blueprint

  1. After applying the faux interior to the glass windows of the building, the interior appears segmented. How can I determine if it looks normal?

Can you help me figure out how to make the left window look like today’s window?
I’m trying to change my existing windows, but there are too many windows.

2.And when you close Unreal and re-enter, the window where the fake interior was applied will appear in green.

I want to solve these issues
Any ideas or input would be greatly appreciated.
