environment texture

I wanted to edit some objects, but I am having problems finding correct .iwi .
Are there any easy ways to find what texture object uses?

Example:
scrap metal covering the window

Unfortunately @Larity2056 is correct it all has to be done manually. In this case, trial and error is your friend.
