Hi Joseph this seems to be a Mac problem. I has to do with broken links to the location of the image. A picture frame is nothing more than a simple surface and an image linked to it. If you select all your Floorplan picture frames (ground floor, 1st floor and roof), go to the properties tab, click on the material button from the top, now open the textures tab if its not already open and click on the link under Color, it should say Floorplan.jpg or something similar. A window will popup where you click on the filename button, here you can select your image. Another window will popup, here you should browse to your PictureFrame directory from the assets and select the Floorplan image.Now repeat the same steps for all your sections and all your elevations.Cheers!Edit: #4 is missing in the image I see now, my bad =)
