Unused Models
There are a lot of mentions for unused models from both the Map Layouts, and from the executable. This contains a list of unused/non-existent & leftover models.
Obj_Bumper (TestObj_BossTamaBank00)
The unused model "Obj_Bumper" (if registered as an actor) will load "TestObj_BossTamaBank00." Walking/Running on the object would bounce you off.
Obj_Box15x15x15
As mentioned in the Map Layout of "Fld_UpDown00_Vss," with the LayerConfigName set to "Tmp," this model doesn't seem to be present in the release.
Fld_Pivot00_DV
As mentioned in the Map Layout of "Fld_Pivot00_Vss," this model does not seem to exist both inside and outside of the model.
TestObj_Lift_Common15
As mentioned in the Map Layout of "Fld_Ruins00_Vss," this model doesn't seem to be present in the release. In the Map Layout, it seemed to be formed as an accessible bridge, allowing you to go to the other side.
