New Horizons:PBC

Introduced in Animal Crossing: New Horizons as a replacement for KCL files, PBC files contain data required for the physics engine to detect collisions. Although ACNH is based off the Splatoon 2 game engine, it seems Nintendo has decided not to use KCL files for ACNH.

Ground Type
Ground type is important for many reasons. The game engine uses PBC data to determine what sounds to play when you walk on grass verses walking on a sandy beach.
