Lighting

Scripting Issues
1

Hi
I’m building an educational video game, my videjuego should have very few requirements. I have problems with the lighting, the models and textures, not that kind of lighting choices. Here I give you some pictures and relevant code. I hope you help me.

1 Problem:

They appreciate the details but stained
code:

 
    Light = AmbientLight('Light')
    Light.setColor(Vec4(0.6, 0.5, 0.5, 1))
    LightR = render.attachNewNode(Light)
    Light2 = DirectionalLight('LightD')
    Light2.setColor(Vec4(0.7, 0.7, 0.7, 1))
    Light2.setDirection(Vec3(1, 1, -1))
    Light2S = render.attachNewNode(Light2)

    render.clearLight()
    render.setLight(LightR)
    render.setLight(Light2S)

2 Problem:

They appreciate the details in a more realistic but the stains continue.
code: Per-Pixel Lighting

 
    render.setShaderAuto()
    Light = AmbientLight('Light')
    Light.setColor(Vec4(0.6, 0.5, 0.5, 1))
    LightR = render.attachNewNode(Light)
    Light2 = DirectionalLight('LightD')
    Light2.setColor(Vec4(0.7, 0.7, 0.7, 1))
    Light2.setDirection(Vec3(1, 1, -1))
    Light2S = render.attachNewNode(Light2)

    render.clearLight()
    render.setLight(LightR)
    render.setLight(Light2S)

3 Problem:
Lighting by default:

No details. The lighting seems not to create spots on the texture.

*how to avoid stains on my model?
*My model is modeled by quads and very few tris.
Thanks for your attention and help.

I’d say the normals on your model are incorrect…

If the second image was created under per-pixel lighting then it may well be that you have incorrect normals on your model.

Where did you get the model – if you made it, then with what program did you make it – and could you perhaps show us a screenshot of the model as it should look, taken from outside of Panda – perhaps in a modelling program?
