//light 1
float3 Light1 = PosWorld - vecSunDir[0] ;
Out.Light1.xyz = mul(worldToTangentSpace, -Light1); // L

Out.Att1 = distance(PosWorld,vecLightPos[0])/vecLightPos[0].w; // Point light

I've tried changing the code, but the sun doesn't seem to affect the model. Which lines were you referring too?

P.S - sorry about my n00b when trying to edit shaders.
