The character generator is a feature of RPG Maker VX Ace, RPG Maker MV, and RPG Maker MZ, used to generate face images and overworld sprites, as well as side view battler sprites in RPG Maker MV and MZ.
In RPG Maker VX Ace, it creates front facing character portraits which do not match the art style used in portraits included with RPG Maker VX Ace's RTP. In RPG Maker MV, it creates character portraits that match the art style used in portraits included with a new game.
In RPG Maker MZ, users are able to adjust the positions of elements on the face portrait such as eyes. In addition, users are able to add additional palettes easily by adding a new gradient to the PNG file for gradients.
Through plugins it is possible to implement an in game character creator.
