In case anyone wants a preconfigured set of mix files:
Instructions:
Unzip the file, drop the folders in ...\ProjectR_Data\StreamingAssets\character\ and overwrite the .mix files when prompted.
Changes:
Player/monster now produces 45% monster 45% human, 5% male monster, 5% elf
Player/woman now has a 50% chance of race matching either player or mother.
Monster/woman now has a 5% chance to produce a woman.
Spellblades are treated as a full race, so you can breed them
Sisters can now produce more sisters. 25% chance when crossed with player, 1% chance when crossed with monster.
Things I'd like to figure out:
Males (basically duplicates of player) can be set to be born, but because they don't have a tab for placement, as soon as they grow they aren't accessible. The baby can be placed in the main room, (appearing grown) but can't be brought to any other room.
