Reply#3 has some instructions.
Updates*3/28/2021: Fix for inputting MDL files that have no deltas on the first frame of the first animation (now inherits data from the bind frame that's not outputted) and a fix that normalizes rotations around the Y axis so they can be upscaled to 60 frames per second in the player (notes in Reply #6.)*4/14/2021: Critical memory corruption bug fix. Edited: Also added mdl2x program. This program is less tested, more experimental. It converts files to Microsoft's X format compatible with SOM's conversion tools. This may be the first time it's been published (notes in Reply #7.)*5/9/2021: More fixes, incl. I bungled mdl2x last time because I added material names to improve it but didn't think to fix the corresponding parts of the file that reference the materials by their names. That's the kind of thing I do all the time (notes in Reply #8.)*5/22/2021: Slight fix for first frame when inputting MDL files (more for diagnostic use) and adding "Original_MDL_viewer.exe" tool (notes in Reply #9.)*7/15/2021: I've attached some source code to this post for safe keeping. You don't need to download it. It's not stored in the official repository with the x2mdl source code because it's code added to Assimp, that's used to read files.12/17/2021: That code (strike-out) is now available with the rest of it (http://svn.swordofmoonlight.net/Sword-of-Moonlight/code/x2mdl/) (x2mdl is now built into SOM and extremely vetted.) The ZIP file is updated with new x2mdl.exe and Original_MDL_viewer.exe and a new viewer called Modern_MDL_viewer.exe that does the same modifications as x2mdl.exe. You probably want to use the latter if you make use these programs. The former (original) is for looking at old MDL files without any changes to their skeletal animation hierarchy and key frame data. Otherwise they're both just quick viewers for MDL and MDO and MSM model files. Also note, there's now a few command-line options for x2mdl.
4/9/2022: KF2-DATA-BACKUP.zip is art from my KF2 project for anyone who's asked for KF2 models in the past. Unfortunately the textures are quite dim. This is how they are on the game disc. You'll just have to increase lighting in your software or process them with image editing software one by one to your need.
