This texture was generated in Filter Forge, a Photoshop plugin that allows you to create your own filters.
Designed to mimic pebbles on a wet, sandy beach around the active tideline. Water washes away the sand around the pebbles where water has been.
A wetness control has also been included in case the same texture generator is used for the beach long after the tide has passed. It should blend through perfectly well with wet or dry.
