A scene needs twenty people standing in it: add a character, place it, add another, place that one — by the fifth you want to give up. The crowd array in DOTV's Previz lines up a whole batch at once — give it rows, columns and spacing, and the batch forms up, after which you work with the whole batch as one thing; a crowd shot in an AI video has its reference in seconds. This section covers lining up a crowd, and moving and changing the batch as a whole.
