all i really want to know is ,what is the best and most realistic way to cast the shadows of clouds onto the scene using vray and max.

many thanks

Hum.... I don't do that very often, but you can use the smoke effect (environment > effects) to create clouds that cast shadows. The clouds won't look all that good, but i kind of does the trick.

You can probably use a projector map of the clouds within sun light. I really haven't done too much with this type of projector, so I'm not sure how you'd get fuzzy shadows. I'm guessing you'd either have to have a semi-blurry projector map or use area shadows in the render.

 

Or, if it's just a still image you can overlay the cloud shadows in Photoshop on their own layer.

Ive done this before.. I made an animated noise map in After Effects, and just put a Gaussian blur on it - looked pretty decent when animated - same thing would probably work just fine in PS
