I already made a thread to this forum about this case a while back but it appears I posted it to the wrong category. Well, I think this is the right place to ask for this.

I also asked about this on Xentax and so far only have gotten one answer, but nothing that really helps in decrypting this stuff.

I'll copy and paste everything I put to this thread on Xentax to here:

Hello, I already made a thread about this to this sub-category in this forum and in the video section, but there really hasn't been any progress on the animations, other than the models, so I decided to just make a new one here.

I've been working on fixing some of the rigs of the models and I've finished doing quite a lot of them. Here are few of them:
https://sketchfab.com/_MaZ_TeR_/collect ... ecromorphs

As for the sake of cracking open the .BNK animation format, I'm going to include the Regenerator type Necromorph. There are three of them but they all use the same animations and sounds.

Here are three enemies that use these animations, they are rigged by me but they do not have correct bone IDs and have most likely incorrect weights:
https://sketchfab.com/models/5dfe049b70 ... 2c6f315dae
https://sketchfab.com/models/41661dda6f ... 6d3f770c45
https://sketchfab.com/models/8d1acae1db ... 645b474980

The Dead Space 3 variant is not in t-pose because I accidentally rigged it out of it. However, the Ubermorph and the Hunter are in T-pose.

The skeleton is included with that model, naturally. However, the bone names are definitely different than to what Visceral Games set them as.

I forgot to switch the scene on 3D max when I was setting the pose of it so it's stuck like that, but as far as I know, it doesn't really matter how the model is posed as the animations will readjust the bones anyways.

Here are the animation files (.BNK) and presumably collision data (.HKX) of this NPC, which I think is useless if you just want the animations:
https://www.dropbox.com/s/gl6vw54pnjl1s ... d.rar?dl=0

There are 8 animations for this enemy:

- Attack
- Death
- Hit react
- Locomotive (Apparently these are the walking/running and in general, animations when the creatures move, the animation state name when looked at on Notepad point at the same direction)
- "Paired" (I have no idea what this is)
- "Scripted" (looking at it on Notepad, this seemed to be the animation when the creature hops in and out of a ventilation shaft and also might be the death animation when the player has critical health)
- "Unique" (No clue what this is)
- "Override" (I have no idea what this is as well)

They are all encrypted in .win format, like the bones.

Here is the bone script I use to get the skeletons, it's quite broken and only gives "red" weights to each bone and does not import the proper bone IDs:
https://www.dropbox.com/s/v340d9yzsij2g ... es.ms?dl=0

Here's the batch version of the model script I use (it doesn't import LODs):
https://www.dropbox.com/s/rtrof1xjrraw2 ... ch.ms?dl=0

Here's another version of the batch script that opens up LODs but it doesn't open up multiple .geo files in a folder like the one above and also breaks the LODs' and level meshes' UVs:
https://www.dropbox.com/s/n4lyc37w04u3w ... -3.ms?dl=0

Here's the content of the attack animation opened on Notepad:
https://www.dropbox.com/s/9wuywsrzv5pej ... k.txt?dl=0

Here is the unconverted skeleton (.RCB.win) of the model I have linked:
https://www.dropbox.com/s/v60xx8v92ce0a ... b.win?dl=0

Here's the content of the file opened on Notepad:

There are some lines missing from the previews but you can find the actual animation and skeleton files above.

This is the skeleton (.RCB) script:

I really hope these could be sorted out some day. These games are quite old so you'd think there was a tool with some modifications done to them can open these. The skeletons can be extracted but the weights are wrong and need to be reset and the bone names are not correct either. So far I have had to re-rig all the skeletons which has taken quite a long time and isn't perfect, but I don't think I should be doing that as they are already ready and just that script has to be fixed.
