A very useful new Monster Hunter World tool has been released today, allowing players to easily change the appearance of their characters in the PC version of the game.

The Monster Hunter World Character Appearance Import-Export Tool allows players to import and export character appearances in shareable JSON snippets. The tool currently only allows to import and export complete character appearances, but it will be possible in the future to just import and export select elements like hair and makeup.
