Thank you for sharing these beautiful backgrounds and tiles.

One thing about the construct: For some perverse reason in default load of the Construct the u=1.0-u=0.0 seam is right in front of the camera. Yes of course in most cases the textures line up at the seam, but why take the trouble. Unless you are using a backdrop and use the costruct textures for light and reflections only, best turn the construct 180 degrees around y-axis so that seam goes where it is least likely to cause concern. .
