I have Brick yard The problem I have is Brick Yard has 20 textures but when I bring it up in Model Builder I only get 19 in the pull down menu the 20 is one that I like and want to use for foundation stones How do I bring this into the menu In case this means anything I also have advertiser loaded in the program Thanks Paul

Brickyard version should be 4.1.1
