Will light works on ET terrain

I want to check whether spot light and directional light works in ET.

For this I disabled the shadow effect and I applied spot light and directional but it is not effecting.

-> What might be the reason for this.

Is there any necessity to write any vertex and fragment programs.

I donot have any knowledge in those procedures.

So, Kindly give some suggestion to solve this problem.

Short answer: Yes with an if, or no with a but.

You must use shaders to accomplish dynamic lighting on ETM terrain. There are several threads that discuss dynamic lighting in this forum. Read through some of them and you'll probably have to learn to write shaders.

I've posted some dynamic lighting shaders, though I did not post one that properly handles spotlights.
