I was reading the recent posts today and remember a post by a user that mentioned he did not have the RWY12 library installed.
For some reason I can find that particular post no matter what I search for so I am just posting a new thread to tell that user to install the RWY12 library along with all the other libraries or you will be missing textures in the scenery that come from that library. Because any of the various required libraries can and are used when the developers make scenery destinations for RTMM you need to have
ALL of the libraries available to your installation to experience RTMM scenery to its full extent.
