Lighting Question

[new_horizon]

I should mention that I am trying to manipulate the 'euro_test19_opt_lite.ive' scene in case you are familiar with it?

Thanks again

The ground has lighting baked into it and does not seem to respond like the rest of the model with real time lighting. You could try blending in a black texture with the ground to darken it so it matches the surroundings. I created a black texture in an image editor and used the following code and it worked ok for a night scene:

blackTexture = viz.addTexture('black.jpg')

ground = city.getChild('ground')
ground.texture(blackTexture,unit=3)
ground.texblend(0.8,unit=3)

lanes = city.getChild('lanes')
lanes.texture(blackTexture,unit=3)
lanes.texblend(0.8,unit=3)

sidewalks = city.getChild('sidewalks')
sidewalks.texture(blackTexture,unit=3)
sidewalks.texblend(0.8,unit=3)

For the sky, you could set the background to different colors instead of using the sky texture.

Hey Jeff,

That's brilliant, thanks so much! I thought that there was something a little strange about the ground lighting and that has cured it!

I feel like I have learned a lot this last week - a large part due to you - so thanks very much for your time - it's very much appreciated!

Hi again,

So texturing the road surface black was a good solution - however, I need to adjust the ambience of the scene and am moving a motorcycle with an illuminated headlight along the road - thus the road really needs to react to that light as well as the overall "sunlight" that I have inserted.

Is there a quick way of developing a ground plain that reacts in this way?

Thanks for your help again,

Mark
