Finding models inside EEMemory.bin files?

Post by SmashFan127 » Wed Feb 19, 2014 11:17 pm

Hello, all. Lately, I've been seeking to get 3D models of characters and monsters in Wild Arms 3 on the PS2, and I was able to find out the 3D data is stored in the EEMemory.bin file extracted from a savestate on PCSX2. I wanna learn how to use shakotay's 3D model extraction guide, but I am uncertain of how to actually locate in hex editors. Can someone please help me? If anyone is interested, I will supply them with the EEMemory.bin from a savestate during the battle with Janus Cascade's demon form.

Well, I have the textures for said character. The problem is finding some way to get the UVs to fit onto them, to help with disassembling model parts.

Have you tried using the WildArms3eememoryto3ds.BMS script? The format specification below seems to mention UVs so they should load.

Of course. I try unwrapping UVs via Blender, but it's in every tri being separated.

Can you send me the file EEMemory.bin file so that I can have a look at it?

Why are you trying to obtain them from a ram dump, what's up with the raw files?
Click the thanks button if I helped!

Supposedly files on the disc use some unknown compression and it's easier to extract data from a PCSX2 savestate.

I really don't intend to put pressure on anybody with this post.

Has there been an update to the situation?

I tried to look at the BMS script to see how it loads the models but it's quite hard to read :oops: I need to look into it later.

My sincere apologies for the bump, but I have recently learned all models in the game use backface culling. Not sure if this will help, but felt like informing.

Due to your question in the tutorials thread concerning another game I restarted viewing the problem here and found it not too hard:

But I have no time to update the bms script so that the uvs are automatically written into the 3ds files in
a 4140 chunk (Mapping coordinates).
(wonder why the author of the script didn't do it. I'm sure he knew how to but maybe he wasn't interested in uvs and normals).

I just made a workaround using a 3ds lib from the web to extract the face indices, and using the bms to dump the uvs.

So I've no one-in-all solution but I could provide the 8 3ds files as objs (including uvs).

Yes, please. :)

It would be appreciated!
