We expect awards to be awarded to the best contestants, so we will allocate all awards in two rounds. In the first round, the engine developer and artists will determine 24 finalists through a series of criteria, namely overall aesthetics, theme and background, diversity, and scene size.

We will announce the 24 finalists and open a public vote to determine the awards based on the ranking of the final votes. The finalist with the highest number of votes will receive the Winner Award; the second, third, and fourth will receive the Outstanding Award; other finalists will receive the Nomination Award.
