Partly Cloudy Day Shadows

[GatesB]

Any one have any suggestions about how to achieve this effect? What I'm looking for is animating those cloud shadows moving across the ground. Is there someway it could be faked?

Just project a cloud map through a light.

Would that work with VraySun as well?

you can also simply use a dome object(flattened sphere) add a texture with transparency map on it and use that. this works with phy sky.
i often mix hdri and phy sky using that technique (hdri in luminance channel) this looks very good, and can produce exactly the shadows you have in reference image

cheers
