Yuke's Pacific Rim .yobj

[OPR23b]

Hello, everyone, I need some help with a model format I've been taking a look at.

I've been wanting to see if I could try to extract the models from a now unavailable Pacific Rim game. However, I have not been able to extract the model data itself.
I've already extracted the files from their .pac files using a PAC extractor, but I've found nothing regarding a .yobj converter/importer (for Blender, at least).

All I really need help with is finding some kind of converter for the .yobj files, that converts them to a format useable in Blender.


I figured this would be a good place to ask, but if it isn't, just let me know.

And if you do need samples for whatever reason, here you go. It's one of the kaiju in-game.

Something's definitely wrong there, but It's for sure the right model file. Maybe it has to do with the face/vertex indices? (I wouldn't exactly know, as I'm not too acquainted with hex side of model extraction just yet.)


To give a better idea how it should look:

Yeah, see, thought it's some kind of landscape or such.

(one submesh only)

I can't seem to find the indices for the other submeshes.

Any idea where they may be? Tried looking for similar patterns but I can't seem to find anything that stands out.

try

0x15112C 20411
Vb1
28 99
0x96F48 9529
121000
0x0 255

(copy above 6 lines into a text file and name it whatever.H2O)

Seems to import everything aside from the other arm and legs.

I'll be seeing if I can locate the last submesh(es) myself, If anything, I'll come back here.
