Fate Grand Order Arcade

Figure I'll throw what I've done in here as well (since apparently some people got a hold of some files before this full dump).

https://github.com/Silvris/RandomScript ... O%20Arcade

Python scripts for unpacking FARC and the tex-bins, and a Noesis script for viewing the resulting .txp.

From what I can tell, the overall file structure mimics those of the Project DIVA games, so anyone looking into the models further should probably start with those.

The Miku Miku Model tool gives "Failed to Open svt_0022_s04_obj.bin Reason: Invalid signature (expected TXP with 3)".

They are read when they put txp file in the file same as obj.bin, but the contents are empty

Ok but those are the model file. Even opening on Hex shows model data.

I only use the bms for unpack the farc, because Silvris tool they only open/close if you move a farc on the bat.

IIRC that's because it's trying to read it as a texture, but even still the formats are not identical, so they shouldn't work in MML at all.

Then how one can open the model data?

And I notice that the bms doesn't unpack every farc.
I have try to unpack other Servants models and gives me the error "can't read 4 bytes from offset 000000000019ca2c".

I've updated farc script with support for zstd compression, which is used in some archives.

This isn't done but I can't look at it anymore right now. This noesis script should load most models. But without bones, weights, and sometimes the UV's are scaled wrong(?!). Also, the vertex normals are encoded somehow and I haven't figured out how. If someone wants to spring off this and finish it that would be great, otherwise I'll come back to this later.

Yes this help! It unpack the ones that cause bms to crash

Cool, this will help for quickly find what each model as it is not truth what the first post say:
Servants order are different compared to the Japanese web, I found the number 09 being the 46 of the web.

For these kind of models all the skeleton info seems to be in a separate folder, this one matches the sample from before:

[Darkhowlings]

I just checked and only 4 servants model didn't load. Also the model order is the same one in which each servant was add and on the version 4.50.00 of the game ends on BB.

This video shows very similar order each servant model data is organize.

Remove other scripts/plugins that attempt to read .bin files first before trying this one.

Ok, I tackled this again. Now it should load most files. The skeleton is in the model files but the bone names don't match, so I don't assign names. Still no bone weights or normals, and UV's are still not scaled.
