Normally when creating a test server, you get blank, grey characters that spawn. The default characters aren’t only boring to look at, but they also don’t do a very good job of testing your game. Your game could have features that depend on accessories (are projectiles blocked by accessories?) or rig type, but because there’s no variance between test players, those cases never get tested.
To reconcile this, I’ve made a plugin which converts test players to use the appearance of random friends:
This should give you better test cases in test servers and make testing less boring. The plugin doesn’t do anything special to players – it only sets player.CharacterAppearanceId – so this should be compatible with any game. This only affects test players, and users in-game or your own avatar in play solo/team test are not affected.
