Best way to add a shadow plane?

[georgy95]

Given there isn't a shadow catcher material, is there an approximation of it using existing materials?

What is the best way to achieve the effects of it?

Hi @georgy95

I don't believe there is a way to do this out-of-the box.
My suggestion would be to write a custom integrator and BSDF for this.

@georgy95 Hi, have you wrote the shadow catcher successfully?
