PyGTK Track Editor - Round 2

[joevenzon]

Do I need to manipulate the object texture to achieve that? Or is there a simple way?

Hmm... if you're using the VDrift scenegraph interface to do you drawing, then you could probably use DRAWABLE::SetAdditiveMap1(const TEXTUREINFO & tex) and DRAWABLE::SetSelfIllumination(bool newsi). The "additive map" just gets added to the texture, so make the additive map in the gimp or something as a small image with a constant color like RGB (0,0,50). A call to SetSelfIllumination(true) will render with the additive map applied, false with it not applied... it's how the brake lights are done.

Now that I look at the code more, this might only work if shaders are enabled. Doh. Another simple way to do this would be to make a simple "selected object" type texture in the gimp and just replace the diffuse texture of the selected object with this texture.
