Transparent material in 3D overlay reflects internal "blue"

[CasperH2O]

Need to look into this:

Coloring the .BackMaterialm solves this issue, as per default models are blue on both sides until colored.

((GeometryModel3D)model3D.Children[0]).BackMaterial = MaterialPlasticBlack;

However, upon doing this the whole model is pretty much transparent invisible.

It's possible to then color this material, but be sure to do the correct render order of the models.

Fixed.
