add specular on uniform volume shader

[soukach]

Hello everybody,

I am trying to add specular on uniform volume shader as in the following link: https://vimeo.com/159216723 (made by Jack Yu).

To make it, he gives us the following explanation:

"Uniform volume shader is a default Houdini shader, all you have to do is convert your particle to VDB then generate the gradient filed, use the gradient field as surface normal to calculate specular in uniform volume shader."

But I did not succeed has to make the last step. Here is my .hip

Thanks for help.
