Altium (another) stupidity: How to un-hide a 3D body that I set with 3D opacity to 0?

Another great stupidity by Altium

I have a 3D body for a LCD module (oh.. I had actually) that was inserted only as free 3D, not a schematic or PCB component.
I just wanted to see how will fits in some PCB cutout. But trying to export the whole project as step for a colleague, I set the "3D opacity" of my LCD to minimum, because he don't need the LCD, will add the 3D model from the Solidworks project.

Everything fine until today, when I want a picture with the LCD... so how can I set opacity back ???

:bang: :bang: :bang:

I tried with another component in my project and that one disappeared too !!! WTF ?!?

Thanks in advance,

The 3D model is by default imported on a mechanical layer in Altium (Mechanical 1 usually). It is thus represented as a pink square in the 2D editor, which you can double click to access its settings and return opacity settings to normal.
