Actually, MrAdults, would you be willing to post some of those AC3 Portable files (I'm assuming it was AC3 Portable) so I can see what other BND formats From has released? I can probably modify my script to handle them all.

unbnd.py is complete! Not my cleanest code, but it handles both kinds of BND file (found to date) and has the option to extract to a subdir of the BND file's dir, or to a dir specified by the user. Works on Linux or Windows. EDIT: I typed too soon. Apparently the object files for the mapdata has the...

No luck tracking down any more info on the model file formats. I'll open up a new discussion in the 3D Models forum on that.
I didn't have time to clean up my python script tonight so I'll post it tomorrow in case anybody else runs across BND files.

Yeah, I dug around in some of the MDL4 files and they're nothing like the 3DGameStudio format. I'm also seeing some SMD files so these might be modified Source file formats, but it seems more likely From just whipped up their own formats and then named them MDL and SMD as a joke - in fact, a 2006 in...

I was able to use the struct and zlib modules in Python to read out the header information and decompress one entry. I'll post a working script tomorrow, and hopefully a picture of a model in the next couple of days! You really saved my bacon, MrAdults!

Great, I'll give this a shot! Thanks, MrAdults!

Hi! I'm trying to get started on a Chromehounds-based Arma2 total conversion, now that the CH servers have been taken down. It's taken me a bit of time but I finally dumped my disk and found that, although the map files are in readily-accessible .mdl format, almost all of the 3D assets I'm really in...
