The Textures and heads are compressed and can be decompressed using this bms script RX3Decompressor.zip

that worked for every texture apart from head_conor_mcgregor_normal.gnf, working in terms of noesis can read .gnf but yeah i get this error from quick bms when trying to do the normal.gnf

It´s because, maybe this files have some extra header.
send me one compressed.

The error of the RX3Decompressor is due to wrong size of block (because of wrong addr)

an uncompressed block.

Not sure about the addr problem:  0xa8ba0

edit: very interesting! I compared the output of Aluigi's script (see some posts below) with my manual extraction, it looks like the block starts with 20E0197E (instead of 28B52FFD). So it's uncompressed data!

------------------------------------------------------------------------------

So I missed that block. (I used: )

So with that bms script, decompressing the textures will make noesis read the .gnf files or will it make the zstdmagicextractor work for the normals also not just the diffuse maps 

it will make noesis read the .gnf files

yeah i got that, good script but yeah like i said above, i cant get the normals to decompress with that

RX3Decompressor.zip

funny enough rx3decompressor worked for the body normal but for the head normal had to use decompressor 

 

update - the rx3decompressor worked for brock lesnar head normal, so i think it varies from different fighter, if a normal doesnt work from that then switch to decompressor, easy does it. well i think thats the texture problem solved for now unless someone makes a noesis script to read the compressed .gnf files, its just now getting the objects with the correct uv maps and cleaning up the submeshes if used by hextoobj. noesis py script for ufc 4 .mcd next step

It's just a different signature of one block (at 0xA8BA0) in the head normal, afaics.

So the trick is, it's uncompressed! And needs to be concatenated uncompressed. Hell, wtf...

Why not always use Aluigi's Decompressor.bms? To avoid any hassle.

going back to this, how do i correct it all to make uvs correct and submeshes cleaned into just meshes so the model can have the textures applied to it properly because at the moment i get this, eyes broken and blocks all over

Try this v2 tool.

Can you test if it works?

Seems head normals is missing the uncompressed block.

The one from here works like a charm:

I’m pretty sure I’m using that obj, but again there’s no eye models included in the head model and its giving me errors, what program is that 

It's pre 2.9 blender.

as the one I sent was a basic tester, full models have separate head, hair, body, gloves, shorts, mouthguard

I checked for the head only (from basic tester).

If you send the separate body I'll check that to give instructions how you can get the rest.

Yes, you can just always run the decompressor ones.

The UV's are upside down, you have to go inside blender uv editor and you have to rotate the uvs 180 degrees for the textures to show up all lined up , alternatively you can flip the texture image itself

Okay thanks man I’ll give that a go, see what I get in my results

heres hair model, cant send body yet as dont know which one it is until i connect model to head model, bodies arent named by fighter, as some fighters use the same bodies

lovely stuff, again sorry im a rookie so i had no idea. if shak-otay manages to do this for all mcd in conor mcgregor files, could have a complete ufc 4 model ripped. problem is though with the bodies being unnamed and just different types of bodies not neccessarily unique to that fighter i cant find which is the right body unless shak-otay did this for all male bodies .mcd which i can assure he wont. if theres a hex value or file that tells us what body he uses then thatll make it easier. once i know the body i know the shorts and gloves. when he gives me step by step on how to do ill be doing it myself.

i think ea uses generic body types for the everyone, you can probably just use the ufc 3 bodies and you'll probably find one which will line up with McGregor, for the eyes and eyelashes you can probably line them up to his model in blender

That’s how I got the Mike Tyson model prepped, I just added each .mcd that I converted to fbx till they lined up and looked accurate. Then I knew the body, then because the body is numbered you just use the same number on gloves and shorts, may use different textures though. UFC 3 bodies may work and connect to his head model but I don’t think they’re the same as ufc 4 bodies 

@Conyaboi: well, I put much too much effort into this so the instructions are kept very condensed, just to say so.

edit: @all: for all those who just step in here: UFC 4 .mcd (and .gnf, texture) are zstd compressed.

Use Aluigi's Decompressor.bms to be found in this thread to decompress them. hex2obj needs an uncompressed file. (Decompressed .gnf textures can be read by Noesis from Rich Whitehouse.)

-----------------------------------------------------------------------------

Checking the .mcd file, Conor's hair:

the FVFsize is 16 for the hair here (but was 12 for the head, as you may remember).

If you run intro troubles getting the parameters for the body feel free to ask. But you'll need to learn some basics of 3D formats.

(Maybe someone will create a script for UFC 4 .mcd files. I, for one, am finished here).

a) Conor's hair in hex2obj (checked one sub mesh only)

:

b) Getting face index start address (search for xndi) :

c) Getting start of vertex blocks (search for MRTS) :

d) Last, not least, the uvs (skipping 2 MRTS blocks of normals, usually) :

HTH

edit: to get the mesh with uvs as a wavefront obj file you'll need to select File\SaveAs mesh

Okay thanks I will try my best to follow this and if i struggle getting parameters I’ll be sure to @ you. You’ve been a big help so I appreciate that. 

@2wrwrw3rw3r did you ever try getting in contact with the person who made the py for the ufc 1-3 models, might be worth seeing if they would add ufc 4 or make one 

 

edit- do you know the .gnf for mcgregors shorts in ufc 3, the shorts with his name on
