Also, could you explain how to get the characters to show up in game? I put the file in the My Games/PolMachine2012/Candidates/Packages folder, but they're not actually in the game. I noticed that my own custom characters don't only have .candidate files but they also have .candidatexml files in the Candidates folder as well as another .candidatecfgxml file in the Config folder.
For now, you should zip up the three files that make up a candidate before uploading.
For example: C:\Users\[username]\Documents\My Games\PolMachine2012\Candidates\Packages\zubaz.candidate
- C:\Users\[username]\Documents\My Games\PolMachine2012\Candidates\Configs\zubaz.candidatecfgxml
- C:\Users\[username]\Documents\My Games\PolMachine2012\Candidates\zubaz.candidatexml
And then unzip them into the proper directories. They will then show up in game.
