Lighting Question

[new_horizon]

Hi All,

I will admit to being a complete Vizard novice and most of the experiments I have been programming have been very basic.

However, now I am trying to conduct an experiment in a virtual scene that has been created - it consists of a number of images of buildings and road etc to create a virtual city environment. The idea is that I will have images moving through this environment, towards the observation point.

My problem is that I wish to manipulate the level of ambient light within the scene. I have tried adjusting the HeadLight...

headlight = viz.MainView.getHeadLight()
headlight.spread(100)
headlight.intensity(100)

...but this makes no differences to how the scene appears.

Perhaps I have made an error, but can anyone point me in the right direction?

Thanks
