It was planned as a 4-5 minute animation of robots and drones landing on an unknown planet and terraforming, but it seems like a simple story of finding traces of people who have ventured to an unknown planet, but in fact, it is an adaptation of the story of "Earth of the Past".
All things are the same, but the basics and basics seem to be the most important.
In CG work, it can be seen as the planning stage.
Since the planning process has no visible output and it is only in the stage of preparation, it is not fun, so if you do a quick sketch and go straight to the production process, saying, 'Oh, this will be enough', you will lose a lot in terms of time and completion of the work later.
