problem about lighting

Hi everyone,

I have some problems about lighting. I copied PSLighting.cg to my own directory of the project. Below there is my material file:
material TerrainMaterial
{
technique
{
pass
{
lighting off

vertex_program_ref Shader/VSLodMorph2
{
}

fragment_program_ref Shader/PSSplat2
{
param_named splatScaleX float 20
param_named splatScaleZ float 20
}

texture_unit
{
texture Splatting0
}

texture_unit
{
texture Splatting1
}

texture_unit
{
texture Toprak_01_0.png
}

texture_unit
{
texture Toprak_01_1.png
}

}

pass
{
// lightmap texture pass

scene_blend modulate

vertex_program_ref Shader/VSLodMorph2
{
}

fragment_program_ref Shader/PSLighting
{
}

texture_unit
{
// dynamically created
texture ETLightmap
}

}
}
}


My shader program:


fragment_program Shader/PSSplat cg
{
source PSSplat.cg
entry_point main
profiles ps_1_1 arbfp1
}

fragment_program Shader/PSSplat2 cg
{
source PSSplat2.cg
entry_point main
profiles ps_2_0 arbfp1
}

vertex_program Shader/VSLodMorph cg
{
source VSLodMorph.cg
entry_point terrain_vp
profiles vs_1_1 arbvp1

default_params
{
param_named_auto morphFactor custom 77
param_named_auto worldViewProj worldviewproj_matrix
}
}

vertex_program Shader/VSLodMorph2 cg
{
source VSLodMorph.cg
entry_point terrain_vp
profiles vs_2_0 arbvp1

default_params
{
param_named_auto morphFactor custom 77
param_named_auto worldViewProj worldviewproj_matrix
}
}

fragment_program Shader/PSLighting cg
{
source PSLighting.cg
entry_point main
profiles ps_1_1 arbfp1
}

And lastly my code which creates the lightmap:
TexturePtr lightMapTex = TextureManager::getSingleton().createManual("ETLightmap", "General", TEX_TYPE_2D,
nHeightMapWidth - 1, nHeightMapHeight - 1, 1, PF_BYTE_RGB);
Image lightMap;
ET::createTerrainLightmap((*pTerrainInfo), lightMap, nHeightMapWidth - 1, nHeightMapHeight - 1,
Vector3(1, -1, 1), ColourValue::White, ColourValue(0.3, 0.3, 0.3), true);
lightMapTex->getBuffer(0, 0)->blitFromMemory(lightMap.getPixelBox(0, 0));

//updateLightMap() Function

Image lightMap;
createTerrainLightmap((*pTerrainInfo), lightMap, 128, 128, Vector3(1, -1, 1),
ColourValue(1, 1, 1), ColourValue(0.3, 0.3, 0.3), true);

TexturePtr lightMapTex = TextureManager::getSingleton().getByName("ETLightmap");
lightMapTex->getBuffer(0, 0)->blitFromMemory(lightMap.getPixelBox(0, 0));


This chunk of code does not work. I compare it with the example, everything is same as i see. What can be the problem?

Please describe how it does not work.

Additionally read your ogre log for errors. If you have a name mismatch, which is a likely simple mistake, it will show up in your log.

there is no error, it just doesn't work.

Please, you must specify what you mean by "it doesn't work". Does it show a white terrain, black terrain, rainbow terrain, ...? Or just a standard terrain with splatting textures working, but simply without lighting?
Are you using D3D or GL rendersystems? Please double-check your Ogre.log, or post it if in doubt.

I am using D3D, I meant lighting doesn't work with it. I does the splatting and mesh deformation. But it doesn't update lightmap and calculate the shadows
