Dear Demian,
thx for the answer.
i added in the attechments, the materials we use on the moment.
The 3rd picture is whit a older enscape where we had the option to turn light on and it would stay in the Illumination 'mode'.
Know i dont know if this was maybe a bug or never intended.
But whit 12-1 pic the light is illumitated, where if i go graphics it will go off.
I do gotta say the light we gave it in the revit familly is all good and will give light in dark. But the lightning fixture will go out.
Like it show in the Pic 12-2.
Pic 3 is the example i would love to create (again), this because most companys that work in models will have the correct collors in the Graphics view/mode.
