Scalar opacity mapping in volume renderer does not save the midpoint and sharpness of midpoint in scene

Hi,
I use midpoint and sharpness of midpoint in the scalar opacity mapping window in the volume renderer advanced option. It works ok.
When I save the scene and reload it - these values are not saved, so the 3D rendering is different from what I saved.
Can you add these parameters to the saved scene?
Thx,
Gal.

Thanks for raising this. This is indeed a current limitation that we will address if this feature request receives sufficient number of votes.
