I was looking for some kids buckets & spades on the 3D warehouse and found this model - thought it looked cool to make a test video from...
The changing of exposure and flickering shadows is because I changed the time and the clouds move rapidly over the sun.
I also made a skateboard ramp and filled it with the sea texture to disguise/re-position the horizon.
When making the 'sand' bump it occurred to me that what I really wanted was to apply a small 'grain' bump to a much larger 'ripple' bump... not sure what other applications that would have, (cloth? hills?) but it would be a really neat feature.
