I did a build of my level and many of the meshes showed up with a “Preview” watermark stamped all over them. Previous builds did not have this. The only thing I had done differently was to put some meshes into newly created folders in the world outliner. I then tried moving some of the meshes out of the folders and re-building, only to continue to get the watermark. I even deleted and re-imported one or two of the meshes (one of them with completely new uv and light map) only to have the same problem occur.
Any thoughts or help on this?
