Since it keeps getting repeatedly asked about, I'll answer the 3D model question.
I created the sprites and 3D model for an earlier version of this mod.
I'm assuming that somewhere along the way, as this mod was updated, that compatibility with the model broke.
It likely broke the moment they added the ledge grab.
I have no intention of updating the 3D model to work with the newer versions of this mod.
I no longer have any association with this mod, because I don't like the direction it has taken, and because of other behind-the-scenes grievances that I cannot discuss publicly.
I have no idea if someone else will update the 3D model to work with newer versions of this mod. It might just get removed, for all I know.
If you wish to use to use the 3D model, you will need to download an earlier version of the mod using the history tab. Version 1.1 should work.
