I have used shader modifiers for Plane but its not working. Can anyone suggest me how to solve it?

let myShaderfragment = "#pragma transparent;\n" + "_output.color.a = 0.0;"
let myShaderSurface = "#pragma transparent;\n" + "_surface.diffuse.a = 0.0;"
 material.shaderModifiers = [SCNShaderModifierEntryPoint.fragment : myShaderfragment, SCNShaderModifierEntryPoint.surface : myShaderSurface]

There's a dedicated lighting model now (SCNLightingModelShadowOnly) to only render shadows
