Find the specific object in your script and apply material to it.

The entire hospital plus ground is one object that has multiple textures.
You need to first remove the entire hospital using RemoveBuildingForPlayer and create it back using CreateObject.
After that you need to identify the exact texture you want and replace it with whatever you want. You do that with SetObjectMaterial.
