I had the same problem and I have found the answer from Advanced_TerrainDemo example file. Here:
import away3d.lights.DirectionalLight;
import away3d.materials.lightpickers.StaticLightPicker;
import away3d.materials.TextureMaterial;
import away3d.textures.BitmapTexture;
...
private var light:DirectionalLight;
private var lightPicker:StaticLightPicker;
...
light = new DirectionalLight(0, -1, 0);
light.color = 0xffddbb;
scene.addChild(light);
lightPicker = new StaticLightPicker([light]);
texture = new BitmapTexture(bitmapData);
material = new TextureMaterial(texture);
material.lightPicker = lightPicker;
Worked for me, hope that helps.

k , iset up a directional lighter and lightpicker , but it seems to not work :
https://www.socialnetworkserver.it/wrball/ -> example
this is the code :
directionalLight = new DirectionalLight();
directionalLight.diffuse = .2;
directionalLight.specular = .3;
directionalLight.position = new Vector3D(0, 200, 0);
lightPicker = new StaticLightPicker([directionalLight]);
scene.addChild(directionalLight);
// in material set up
mat.lightPicker = lightPicker ;
mat.bothSides = true;
it seems no plane is affected by lights!

The above does not work for me:
caseMaterials = new TextureMaterial(new BitmapTexture(caseBMD))
caseMaterials.ambientColor = 0x505080;
caseMaterials.gloss = 500;
caseMaterials.specular = .6;
caseMaterials.lightpicker = lightPicker;
gives me the error:
Error: Access of possibly undefined property lightpicker through a reference with static type away3d.materials:TextureMaterial.

@bardo : Yes, my plane is definitely affected by the light, because I can see the difference when I do not set the lightPicker property.
@Margeret : the correct line should be “caseMaterials.lightPicker = lightPicker;” where the property name is “lightPicker” with capital “P”.

@thoram : as u can see from my link , no planes are affected by light: the light is in the center of the sphere , i expect shadows on the etrnal surfaces , and light on the internals ... maybe is the bothSide property the problem?

quite solved ... guys the frame rate , with a lot of path animator and lights , is impressive. at 25fps base , i have an average of 26.
i love the away3d team.
