I have the lights placed next to a wall that is connected to the terrain. I have the range set so that it more than encompasses the terrain, but it still is unaffected. That's why I think it is the shader that IceX applies

if you are using a shader on the terrain, it wont use the satndard A6 dynamic lighting system. This means you have to calculate the lighitng in the shader. You can use vecLightPos and vecLightColor shader vars to help you. Remember, only dynamic lightis will be passed to the sahder.

I looked through the shader that it uses and I don't recall seeing those variables referenced anywhere, so that must be it. I'll have a look at the manual and try to figure out how to implement them from there.

Thanks for that info, and by the way I think I will be purchasing Sphere from you soon.. Your plugin is absolutely amazing
