Hi Ollie:
Looks like you're making more good progress.
Before we proceed into the relatively complex workflow required to make a sloped flatten 'intended to be blended' into the surrounding and underlying 10 Meter resolution terrain mesh cited above (...in the new thread within SBuilderX forum), I wanted to verify what the P3D run time display status is for the tank object after it is saved as a scenery *.SXML file, compiled into a scenery library BGL, and then placed by a BGL.
Did you try slewing over to it in P3D without SimDirector running, to inspect and confirm that it is NOT showing Pitch or Bank ?
If so, you may not need to create a complex sloped flatten as a base on which the sewage processing tanks are placed and displayed, as you can extend the depth of each such tank 3D object bottom, and place them all at a negative Altitude AGL by pulling them down farther onto / into the ground plane in FS with the SimDirector 'Translate Gizmo'.
Reportedly, you can do this even if the "AltitudeIsAGL' mode is set in the SimDirector GUI, and without assigning an Altitude AMSL.
It is rather late in my time zone, so, pending your response to this latter question, I shall reply accordingly tomorrow (Sunday).
