Worldspawn layers example map liquid physics don't seem to work

[monkeyvault]

I couldn't find a visual reference to the intended behavior, but the physics balls just glide on the "liquid" surfaces at even velocity.

Godot 4.2, Qodot 2023.3.2.

Same, and when I try to rebuild the map, The physics_ball objects are loaded as QodotEntity instead of RigidBodies. I added the physics_ball_class.tres to the qodot_fgd resource, but it doesn't seem to recognize it.
