The Big Pal Project adds in a small dynamic weight gain system to the pals in palworld. The system works by tying the pals hunger to their size, causing pals to look like they are gaining weight as you feed them and loosing it as they get more hungry. The mod also supports different gain shapes according to the pals gender allowing for different types of gain between male and female variants.
While the mod started off strong with a biweekly release cadence it began to slow down around version 0.4 before fully stalling out at version 0.5. It was stated this was due to having no more modelers on the project as most of the original team has moved onto other projects or simply only planned on contributing a few pals they had interest in. The lead programmer, grotlover2, did state they plan on trying to continue to support the mod the best they can but said any new models or fixes to current ones will likely not happen due to the lack of a modeler to handle them.
The mod was opensourced on github on 1/6/25 with the 0.5.1 release in order to allow the community to contribute to the mod if they wish.

. If UE4SS installed correctly you should see a LogicMods
folder in there along with a Pal-Windows.pak
file which is for the base game.Pal\Content\Paks
The mod may not look like it is working. If that is the case ensure the pal you are tested is implemented and that UE4SS is installed correctly.
