Hi everyone,

I am trying to render out a Z depth image of a simple scene. I have 2 shaders: a surface shader that collects the depth information and an imager shader to put a solid background color behind the image.
rmands gives an “Unknown shader type” message on the imager shader.
So I wonder:
-How can houdini use that shader?
- How does houdini make Z depth image with renderman?

Any help will be appreciated. Thanks
