It seems that the glass parameter described in the SDK (See attachments) are missing completely in the Blender exporter? Is it outdated information in the SDK or is it missing in the exporter?
Repro steps: Open blender, Create glass material, observe issue
Please allow me to also add that the parameters are also missing in the version 4.2 LTS addon for blender.
It would be greatly appreciated to have them back, right now my gauge glass looks awful in game as the reflection mask parameter is missing, thus my gauge glass is reall really reflecting.
