Wall texture making this duplicate room unconvincing

Help and Feedback Building Support
#1

I made a duplicate room for the player to be teleported to. The walls are using the roblox material “concrete”.
The problem is that the way the texture of the material is applied to both rooms is not identical, meaning that when you get teleported from the normal room to the duplicate room, it’s pretty easy to tell.

Is there any way I can make them identical?

Turn off Shadows on the parts of the rooms, that would be the only difference if the rooms are truly identical in all other ways.
