groundmaterial DirectionalLight and WORLDMONGER.GroundMaterial

[JonathanRev]

Hello guys ! i was working with groundmaterial several weeks already , but i recently noticed that  "DirectionalLight" is not a good friend of "WORLDMONGER.GroundMaterial" i hope i am wrong ,

but i was experimenting with endless landscapes and i noticed that when i go far from the point 0 , 0 , 0  of my scene the diarectionallight doesn't iluminate with the same intensity when i go far away from point 0 , 0, 0 when i use the GroundMaterial

i set the directional light this way :             var light = new BABYLON.DirectionalLight("dir01", new BABYLON.Vector3(0, -1, 0), scene);
                                                                         light.intensity = 1.0;

and i am using the groundmaterial as :     var groundMaterial = new WORLDMONGER.GroundMaterial("groundMaterials", scene, scene.getLightByName("dir01");

                                                               -----------------------------------------------------------------------------------------------------------------

Now when i use a the StandardMaterial :  var groundMaterial = new BABYLON.StandardMaterial("ground0", scene);

                                                                         groundMaterial.diffuseTexture = new BABYLON.Texture("shaders/Ground/grass.png", scene);

and i move far from the point 0, 0, 0  it works perfect and iluminates with the same intensity for example if i were some kilometers far away from the point 0,0 as it would be on the point 0,0 

is this really something related to groundmaterial? , or i should use some trick to have kilometers of my scene with the same intensity in light using directionallight and groundmaterial?

i have already tried using the scene.registerBeforeRender(function() to have the directionallight follow the camera but i don't think it is a good solution , i guess the DirectionalLight should iluminate the same ortogonal way even if i am far away from the initial location point of the directionallight.

Hey!

the ground material assumes that you are using a point light:

wow ! totally right , i guess i fixed it this way , i replaced : 

                                                                  // Light
                                                                  vec3 lightVectorW = normalize(vLightPosition - vPositionW);

by this :  

                                                                   // Light
                                                                  vec3 lightVectorW = normalize(vLightPosition);            

Not sure if this will have any effect in another part of the game, but now it iluminated perfect in all directions !
