Revit to LumenRT - Section box around model causes a 4th floor model to come in under the ground level - Can we export without the terrain option?

Title states the issue, video shows this issue:

  • Yes, within the folder in which LumenRT is installed on, search for OptionDlg.exe, launch it and set the Terrain to either Flat Desert, Flat Pavement or Simple Ground and then press Start, unless specified, all export to LumenRT should default to that Terrain.

    Not sure about getting rid of the Terrain entirely as my attempts to delete objects using Python API, have led to LumenRT crashing.

    Default path:

    C:\Program Files\Bentley\Bentley LumenRT CONNECT Edition - Update 11\LumenRT\bin\OptionDlg.exe
