PyGTK Track Editor - Round 2

[rookie1]

I've pretty much came to the same solution as your first suggestion. Unfortunately it doesn't seem to work. I"m using data/textures/effects/white.png as the additive texture. There is no visible difference however. Did I miss a step? Here is the python code,

Code:

#highlight selected object
    texinfo = vdrift.TEXTUREINFO()
    texinfo.SetName("textures/effects/white.png")
    pyobj.drawable.GetPtr().SetAdditiveMap1(texinfo)
    pyobj.drawable.GetPtr().SetSelfIllumination(True)
    self.trackwindow.queue_draw()

On a side note, why do we need shader=on to have brakelight?
