Hey,

I have an object I want to be rendered in Renderman/RIS. But I want to keep its shadows but not the plane under it that catches the shadows.

When I use Maya's default use background shader it just shows it as a diffuse shader in RIS.

I've also tried rendering with a shadowpass, but I tried and maybe I did something wrong but it didn't work. So does anyone know how to render a shadow but not the plane that catches the shadow?

Is there like a use background shader in RIS? I know Reyes has one but I couldn't find it in RIS.

Thanks in advance.
