[Question] Is it possible to set the face.normal?

[Pixero]

Anyone getting more than one line to work?

I only got to change some OpenGL Server variables like GL_COLOR_MATERIAL or GL_DEPTH_TEST.
I don't know the way to hack into drawing context. I wonder how it is done in LightUp (supposing it is done similar way), maybe a window is layered on top of native SketchUp viewport.

I don't think Lightup does this. I think it renders materials and bakes them into faces in SU. At least that is my (severely limited and naive) understanding.
