Anisotropic Material

[ParaToxic]

Hey I would like to ask you where I can find the shader code for example changing the light model ( I think it's phong now ) ?

I can't find it in the mesh.frag shader, but I saw in the Lighting folder for example in the DirectionalLight.frag file , that there are some modifications, which looks like that what I'm searching for.But now the question is, which vertexshader do that lighting-pixelshaders use ?

I need to add the Tangent and Binormal variables to create a anisotropic material.

 

EDIT: I forget, it's a deffered renderer So is it possible to get the tangent in the lighting shader ? Caus' I need the normal ( is available ) and the tangent -> compute the binormal.

 

 

Thanks
