Clumped characters from Project IGI *.MEF

[mrmaller1905]

I tried Hex2Obj and Noesis plugin but I got clumped characters. Can someone fix this?

How far did we get on Xentax with these .mef? I feel we were done.:D

You could use the output of Durik's script for 015_01_1.mef

to find out where some "positioning" matrices are to be found,

maybe in section D3DR or TAMC (what do these signatures mean? Direct3D rotation, etc?)

btw, "chank" might mean "chunk" (but not sure)

What is .iff and has anyone tried to reverse engineer this and convert to .fbx?

Can someone help me fix this clumped character by making a new Blender or Noesis plugin for IGI 1 or other tools?

That honestly looks like a skinned character whose IBM has not been properly applied

[mrmaller1905]

So, here is the download link for the MEF converter scripts in Python

Did you try out one of the commands?

I get ModuleNotFoundError: No module named 'lxml', so using pipinstall might be required.

Here is the binary template for IGI 1 .mef

Sadly  pfp can't process this bt line

switch(ReadString(FTell(), 4))

(not implemented error)

 

[h3x3r]

I think you can replace it with if/else function

Looks like these values are responsible for mesh position.

Edited March 4 by h3x3r

[shak-otay]

Problem is not the "switch", it's the ReadString() (should have been more precise, sorry).

[h3x3r]

Try this one. But i think that local variable will be problem here.

local string Sign;
struct
{
    ILFF_HEADER header;
    CH formatid[4];  // OCEM

    while(FTell() < FileSize())
    {
        Sign=ReadString(FTell(),4);
        
        if (Sign ==  "HSEM")
        {
            HSEM hsem;
        }
        else if (Sign ==  "ATTA")
        {
            ATTA atta;
        }
        else if (Sign ==  "XTVM")
        {
            XTVM xtvm;
        }
        else if (Sign ==  "TROP")
        {
            TROP trop;
        }
        else if (Sign ==  "XVTP")
        {
            XVTP xvtp;
        }
        else if (Sign ==  "CFTP")
        {
            CFTP cftp;
        }
        else if (Sign ==  "D3DR")
        {
            D3DR d3dr;
        }
        else if (Sign ==  "DNER")
        {
            DNER dner;
        }
        else if (Sign ==  "XTRV")
        {
            XTRV xtrv;
        }
        else if (Sign ==  "PMTL")
        {
            PMTL pmtl;
        }
        else if (Sign ==  "HSMC")
        {
            HSMC hsmc;
        }
        else if (Sign ==  "XTVC")
        {
            XTVC xtvc;
        }
        else if (Sign ==  "ECFC")
        {
            ECFC ecfc;
        }
        else if (Sign ==  "TAMC")
        {
            TAMC tamc;
        }
        else if (Sign ==  "HPSC")
        {
            HPSC hpsc;
        }
        else if (Sign ==  "TXAN")
        {
            TXAN txan;
        }
        else
        {
            Assert(false, "Parsing error: unhandled block type");
        }
    }
} igi1_mef;

or change function on ReadUInt(FTell()) but you must also change exception value to uint. > if (Sign == 1296388936)  // HSEM sign

Edited March 4 by h3x3r

[shak-otay]

Thanks. That problem solved.

local UINT32 Sign;
local UINT32 x;

struct
{
    ILFF_HEADER header;
    CH formatid[4];  // OCEM

    while(FTell() < FileSize())
    {
        x = FTell();
        FSeek(x);
        Sign=ReadUInt();
        
        if (Sign ==  1296388936) //HSEM
        {
            HSEM hsem;
        }
        else
        {
            Assert(false, "Parsing error: unhandled block type");
        }
    }

But the next error to appear:  "could not resolve field header". (I had to insert the include .bt files into the main bt). 

error line:     if(header.chunksize > 0)

I think, I'll need to wait for an update of pfp master.

What is .cmd  .ctr and .hmp and does anyone have an idea to start a new terrain editor that creates custom terrains?

Well, I know, you're constantly switching between hundreds of requests so I don't know how deep your interest is in this one.

I compiled the project and seems it's a terrain viewer:

If anyone is competent to develop an IGI terrain editor then the author of this project should be. Why not ask him?

There's also another project that could come in handy (but it's not a terrain editor).

edit: I read a review that said/confirmed the environment being "bleak and boring" so dunno whether it's worth bothering. (If you don't suffer from nostalgia it would make more sense, imho, to care for games with modding tools, such as "Beyond Enemy Lines".)

Recently Jones-HM has released a 3D terrain editor which allows authors to create custom missions and terrain models.

https://github.com/jones-hm/project-igi-toolkit

[shak-otay]

I didn't expect Jones to be still working on this. The feature "Level ToolKit" of the igi-toolKit would be the first thing to use (if I had the game).

Ok analyze the source code for this repo and see what the IGI 1 3D level editor can do.

Alternatively, you could analyse it yourself instead of just demanding people do it for you.  Just download the release and try it.

Excuse me I'm looking for a Blender plugin that exports custom IGI 1 MEF files with support for bone models.
