[Allegro] bad 3D rendering (uniform color) on some STEP file components

 Hello,

I've got a problem with the 3D view of my board.
Several components have a bad rendering, the color is uniform on the component.
The component seem to be good when i'm in the package mapping tool and when i open the step file with an external step file viewer.

You can see on the following images a bad component (SMA) and a working component (0603 resistor).
The first image coming from an external step file viewer, the second is from the package mapping tool and the third is the 3D preview.

I've attached the step files if you want to try by yourself.
My Allegro version is 16.6 S020

Where do the problem come from?

Thanks,
Eric.
