Material Stylesheet Won't Override Principled Shader?

[Atom]

HI All,

 

I have a simple lava setup where the lava flows over some obstacles. This works fine.

I am using the default lava1 shader that was generated by the shelf tools.

I have created a new attribute on the points called my_emit_int and set it to the value of 1.0.

I have manually set the emitint for the lava1 shader to 0.0. Thus the grey matte look of the fluid.

I am using the following stylesheet code to override the exiting emitint with my_emit_int.

// Houdini 15 style for stylesheets.
{
    "styles":
    [
        {
            "target" : {"pointGroup" : "*"},
            "overrides" : {
                "materialParameters":{"emitint":{"script":{"binding":"my_emit_int"}}}
            }
        }
    ]
}

This stylesheet code produces no errors when rendering but it also does not work. my_emit_int attribute should take over the emitint value and set it to 1.0. This is not happening.

 

What is the syntax for the stylesheet that I should use to successfully override a material parameter with an attribute?
