Introduction:
Always we need a white ground with shadows, there is no visible white ground at the reflections, And this workflow is a good workaround for this problem.
If you can put out a better way, please do so.
How:
* Create a plane material and disable “double-sided” at the VfR material. Now, you can render the plane from the bottom view – you should see the shadow.
* Crop the image so that the rendered plane can be used as texture.
* Create a new material, set color complete black and set the previous rendered ground texture as transparency map.
Now, your ground plane should be show a shadow only, nothing more. Maybe you need a little bit fine tune the texture at photoshop.
Here a quick test – background is added in photoshop.

The ground texture can be used for the Rhino rendered viewport – here a screenshot with “baked” softshadow + hardshadow.
