Transparent 2d Silhouettes(people) and transparency

I have the White Mode set in Enscape (using with SketchUp).

I know that all items go white unless they have a level of transparency designation using Enscape materials.

The 2d silhouette people I am using are just outlined 2D single planes (no thickness, no textures). Standard SKP.

No matter what I do I cannot make the silhouettes have any transparency. I just don't want them to be completely solid in the "White model"

Thanks

After some further testing it seem that if the 2D geometry is a SkecthUp "component" it is not recognizing the transparency of the material. As soon as I "explode" the component it recognizes the material transparency, BUT unfortunately I cannot use the "face camera" property if the person is not a component. Any advice on how to solve this?

Thanks
