Changing shadow color and opacity inside shader?

[Anonymous]

Hey Arnold Community!

I have a question regarding stylized rendering.

Question: Is it possible to change the shadow color and shadow opacity of an object inside the Arnold shader?

What I want to achive is the following:

Inside of the PxrSurfaceShader you can change the color of the shadow per shader.

I found the possibilty to do this in the Arnold light:

But this would make it quite complicated to have a separate light for every object.

I tried doing it with the aiRaySwitch but did not get how to setup the shadernetwork.
This is my failed attempt, maybe someone can show me how to do it.

I am trying to achieve a 2D look and this would help to soften certain objects. For example having a bush and letting the shadow only cast at 20% through the leafs and making it look softer.

Thanks for your time,

Alex

You do what it shows in the screenshot
Then use the Opacity color in the standard_surface connected to the rayswitch. That will change the color of the object's shadow.
