Hi,
On which source code file i can get the source of the Lightmapping shader?
I am not good at source mining but i really need that for study...
Any helps appreciated...
thanks in advance...

I don't think you need a shader for this technique of lighting since lights are baked into textures (?)
PS. Why do you put "..." after most of your sentences?

@skumar: AFAIK Irrlicht is not using a shader for the lightmap materials. It`s using some blend states for this, as its extremely easy. But, in a shader you`ll simply need a color sampler texture and a lightmap sampler texture, usually 2 texturecoordinate sets, which you pass from the vertex to the pixel shader and you do:
Code: Select all
float4 finalColor = sampledTextureColor * sampledLightMapColor;
return finalColor;
Can`t be easier than that. Well, some extremely basic shader knowledge is needed though.

He does this because recently there`s a shortage of "."-s in the forum because of this guy, who never puts single periods in his posts:

I was taught otherwise at school.
