How could Toony tool pro 2 support point/spot light?

Hey, I am a beginer in U3D and got a problem when using Toony tool pro make the cartoon shader.
with Tonny tool pro,the shadow color could be set as costum color.
But now this function just works when the light is directional light.
Did I missed any setting of the plugin or U3D?

the shader is Hybrid Shader, bule shadow from the directional light, grey shadow from the point light(it should also be blue)
