Headlight Question

[new_horizon]

Thanks for the reply Jeff - I decided to try to use the Inifinite Terrain and coat it in a tarmac image in order to increase the tesselation...

#Add a texture and set it to repeat mode.
grass = viz.add('tarmac.jpg')
grass.wrap(viz.WRAP_S,viz.REPEAT)
grass.wrap(viz.WRAP_T,viz.REPEAT)


#Add the terrain using the infinte terrain plug-in.
terrain = viz.add('InfiniteTerrain.dlc',1,'456',8,1000,400,1 0000)

#Texture the terrain.
terrain.texture(grass)
terrain.command(1,'',0,0)
terrain.appearance(viz.TEXMODULATE)

However, I am still getting this jagged light effect - almost as if it is passing the light onto one object and then another - just at a faster pace. Is there anyway of smoothing this? Any increase in tesselation value (over 8) for the terrain results in my PC crashing - if an increase is likely to improve this effect, I can find another PC.

Thanks - I appreciate your help!
