I want to open this 3D model from the PS2 game Digimon World Data Squad, but I haven't been able to open it with anything. Can anyone help me?

Looks to me like animation curves:

Here you can see something, but I don't know how to find the faces.

Hi Reh! (Reh from former Xentax?)

PS2 models are known for using auto created faces. Doesn't work here, so maybe a split up of this mesh is required?

edit: tried steps of 120 vertices but even this obvious head gives a bad result when using fake faces.

Hi Shak-otay, yes it's me, I never imagined you would remember me 😄.

I found this texture in the file.

Sir~ You're right. The top-level data contains something like 00 00 80 3F alignment, which seems to be the matrix coordinates of the skeleton and chunks. The vertices are stored as short integers. Under each chunk, there appears to be some kind of bone mapping table for vertex assignments. As for the face indices, they are not that easy to understand... I've tried using some common connection methods in the data, but the results aren't ideal. Maybe it's exactly as the person upstairs said: the faces are automatically created and connected.

I remember having checked this on former Xentax around February 2020 (but don't remember the results, if any).

Meshlab is an option:

but on a quick shot it's ugly like hell:

Point cloud skinner (in blender), result looks janky, too, but could serve as a base:
