Adding sun specularity to TSE water

Find shaders/water/waterCubeReflectRefractP.hlsl about line 108 or so find a line that reads

// 2:  This almost looks good
   /*
   bumpNorm.xy *= 2.0;
   bumpNorm = normalize( bumpNorm );

   float3 halfAng = normalize( eyeVec + IN.lightVec );
   float specular = saturate( dot( bumpNorm, halfAng) );
   specular = pow(specular, specularPower);
   OUT.col += specularColor * specular;
   */

Now either uncomment or replace it with:

// 2:  This almost looks good
   
   bumpNorm.xy *= 2.0;
   bumpNorm = normalize( bumpNorm );

   float3 halfAng = normalize( eyeVec + IN.lightVec );
   float specular = saturate( dot( bumpNorm, halfAng) );
   specular = pow(specular, specularPower);
   OUT.col += specularColor * specular;

This looks pretty neat in my opinion.

Enjoy!
