The transparency setting was connected to the material of the volume.
This led to the same transparency setting for all volumes of the same material.
It was not possible to change them at the level of the volume though
the API suggested so.
See: New visualisation by reference edits alpha value of referenced VisAttr #1117
See: Allow geometry transparency at the volume level root-project/root#13402
From the inversion of tubes with the same material, for ROOT >= 6.29
the correct transparency settings are shown, whereas for ROOT < 6.29
the transparency settings are the same for all volumes.
