January 26Jan 26 I'm digging more and more into figuring out how to extract these meshes from the game Medal of Honor: Frontline (and Rising Sun) for the PS2. I've already been able to get the sfx/music so I have a little experience in using a hex editor. I would really appreciate anyone able to help me make sense of what I am seeing for mesh data, or at least get a fresh set of eyes to explain things better. I've looked through a few of the tutorials and will continue to research but I'd like to get this out there in case someone wants to take a jab at it. I have manually extracted the asset below from the parent archive (which seems to be some sort of BIG file? 0xC0FB magic), and it is quite a bit bigger in size from a previous attempt using a tool that was made for those types of files, but I don't think it's useful for this game. I can see floats and other groupings of things but I just can't make sense of them with the knowledge I have at this point. To me, it looks inconsistent. I also have Model Researcher and Noesis on-hand. Thank you for your time. Vehicle_Jeep_Wheel.zip
January 26Jan 26 Supporter I'd guess for VIF tags but the resulting point clouds are ugly. Maybe upload a bigger part of the jeep?

I've also attached some pics for the header of the archive, and of the offset/size/name of the files produced, if it helps. The second result in the search is just the names. Vehicle_Jeep_Body.zip
January 26Jan 26 Supporter Thanks! I gathered 7 sub meshes, it looks like something but would require much fiddling for a better result: edit: when interpreted as uv data it looks smarter. (But times where I spent hours with PS2 VIF blocks are over...) Edited January 26Jan 26 by shak-otay

PS2 must be doing a lot of interpretation type stuff then? I'll take a look at the Xbox and Gamecube versions.
January 27Jan 27 Supporter Also not sure if there are any submeshes. There's uv overlaping Textures are inside too. Edited January 28Jan 28 by h3x3r

January 28Jan 28 Supporter So the palette format is BGRA8888 instead of RGBA8888. Thanks for confirming. BTW what is your goal? You want whole level or just models? Well this is everything I know so far about *.msh format. But don't know how to assign material to the mesh. Mesh has offset to the material. *.mpk also include meshes + textures.

UV's are flipped after export. Not sure why Noesis does this, when I preview uv in noesis they are correct. So if you want export check the Flip UV's in export options. from inc_noesis import * import noesis import rapi import os def registerNoesisTypes(): handle = noesis.register("Medal of Honor Frontline - Mesh", ".msh") noesis.setHandlerTypeCheck(handle, noepyCheckType) noesis.setHandlerLoadModel(handle, noepyLoadModel) noesis.logPopup() return 1 def noepyCheckType(data): bs = NoeBitStream(data) if len(data) < 20: return 0 return 1 def noepyLoadModel(data, mdlList): bs = NoeBitStream(data) baseName = rapi.getExtensionlessName(rapi.getLocalFileName(rapi.getInputName())) ctx = rapi.rpgCreateContext() Underline = "_" bs.read(24) MeshTableOffset = bs.readUInt() MeshIndex = bs.readUInt() bs.seek(MeshTableOffset, NOESEEK_ABS) for i in range(0, MeshIndex): bs.read(8) MeshOffset = bs.readUInt() bs.read(20) cPos = bs.tell() bs.seek(MeshOffset, NOESEEK_ABS) bs.read(12) VertexBufferOffset = bs.readUInt() IndexBufferOffset = bs.readUInt() VertexCount = bs.readUShort() IndexCount = bs.readUShort() MeshIndex = "{:04d}".format(i) bs.seek(VertexBufferOffset, NOESEEK_ABS) VertexBuffer = bs.readBytes(VertexCount * 28) rapi.rpgBindPositionBufferOfs(VertexBuffer, noesis.RPGEODATA_FLOAT, 28, 0) rapi.rpgBindUV1BufferOfs(VertexBuffer, noesis.RPGEODATA_FLOAT, 28, 20) rapi.rpgSetName(baseName + Underline + MeshIndex) bs.seek(IndexBufferOffset, NOESEEK_ABS) IndexBuffer = bs.readBytes(IndexCount * 2) rapi.rpgCommitTriangles(IndexBuffer, noesis.RPGEODATA_USHORT, IndexCount, noesis.RPGEO_TRIANGLE_STRIP) bs.seek(cPos, NOESEEK_ABS) mdl = rapi.rpgConstructModel() mdlList.append(mdl) return 1 Edited January 28Jan 28 by h3x3r

But don't know how to assign material to the mesh. Mesh has offset to the material. Thank you so much! That's more than I was expecting. Also saves me from figuring out why my script wasn't working right, lol. Ideally, I'd like to get models (props + characters), maps, animations, textures... sfx and music is easy enough. There are a couple reasons: nostalgia of course, I played this game to death on the ps2 and it's what makes me want to do this. Preservation of the game and its assets. And also modding or possibly fan projects in the future. Ah, the Dutch town mission 😉
January 29Jan 29 Supporter Well i figured materials for level meshes. I noticed they are using external texture id but still one thing remains, some of them use internal textures and don't know yet where is texture index for them. Like i know it is in material but don't know which value it could be.

Like i know it is in material but don't know which value it could be. So is everything for the levels in the .cpt? I've taken a peek into the .cdb but not a lot stands out to me at the moment. Was able to get textures onto the vehicle in Noesis, just gotta figure out why the glass texture is still not right.
January 29Jan 29 Supporter Yes, cpt is level. Anyway good work with assigning textures. Can you show me how you did it? Here's Noesis for any kind of *.xsh.

January 29Jan 29 Author Still figuring out how to handle that last texture with the transparency. The texture before it is empty so it skips it. But I think they are connected somehow.

January 29Jan 29 Supporter BTW did you figure out what's goin on with comp.viv which has C0 FB signature? Can't see any value representing offset/size. Maybe it's converted. Normaly when signature is BIGF there is uint32 Offset and uint32 Size and string Filename. But this one has only 6 bytes and then string as Filename. EDiT: Well i found something. The data type is uint16 and is multiplied by 256 but for the first file is wrong file strats at 384 bytes and I get 256. Damn when file count change the value too I am lost here.... At least file size is written right after 4 byte sign. Maybe use findloc function solve this crap. Here's 2 samples if anyone want to take a look. I bet DKDave would crack this... viv.7z The cdb = most likely collision database Edited January 29Jan 29 by h3x3r

Apologies if I misunderstand. I'll post a pic of what seems to work for me. A while ago when I first saw C0FB, I thought it was some type of compression; now I think it's just a different way Electronic Arts packed some of their game archives. There is a modding program for some of the SSX (snowboarding) games that can open BIG/BIGF/C0FB files (it doesn't seem to unpack these well, however). It is strange that it is 6 bytes + string for each file... So big endian, offset 0x06 = 0x000180, go to offset 0x180 for file start, offset 0x09 = 0x063064 for 405,604 bytes in length. Then some alignment padding before the next file starts at 0x63200, etc. Looking at it now I see that 0x000E is indeed the file count, lol. I have it as "unknown" in my earlier pattern in the pic.

Thanks, I'll add this to my collection 🙂 Also I've realized that my solution to get the jeep textures in Noesis ONLY works for the jeep model so I have some troubleshooting to do. I think something weird with getting palette data. Also been working on the sequel, MoH: Rising Sun, and have had some success but I'm having trouble finding mesh table/offsets. The game was released just over a year later but the formats are slightly different. I can get the models and sub meshes manually but I'd rather have a script. Mind taking a look? I'll send a couple examples. The data blocks so far seems to be: Header? Face index Vertex buffer UV buffer Unknown Unknown Unknown Header? *Includes file name Then it repeats. I've taken a look at the bottom of the files but I can't seem to make sense of it. I've attached some troublesome files. MoH_RS_testing.zip
February 1Feb 1 Supporter About palette. Seek paletteOffset and seek another 8 bytes back and read uint32 and miltiply it by 4 and you'll get palette size. You can do this i think: bs.seek(paletteOffset - 8, NOESEEK_ABS) paletteSize = bs.readUInt() * 4 go back to paletteOffset and read palette buffer. rawPal = bs.readBytes(paletteSize) Edited February 1Feb 1 by h3x3r

Why is a multiple of 4 used, though? Either way, there are textures that do not use palette data so that's the next thing I'm looking at. I also think it is BGRX instead of BGRA, will do more testing. Edited February 1Feb 1 by MrGravey added info
