Do you have a tutorial on how to do it? With images maybe?
Yes, I have the tutorial, but it is in Russian. I tried to write it in simple words, so Google-translator translates it with almost no semantic errors: link
Here is a bit better translation:
To extract 3D Models from Telltale Games archives you will need atleast two instruments:
1) Telltale archives extractor "Telltale TTARCH files extractor/rebuilder" from Luigi Auriemma. This is cmd.exe program. It almost always updates, by it's author, you can always find the latest version here: http://aluigi.altervista.org/papers.htm#others-file
"Telltale TTARCH files extractor/rebuilder" Download link is in the description of it's website
2) RandomTBrush script for 3DS MAX, that allows you to import meshes and their armature. Not all TTG games are work with this script. The list is here viewtopic.php?f=16&t=11687
Besides script for 3DS MAX, in archive you can also find a program called "QuickBMS". You will need this scripts and the program itself for convert textures from the latest TTG games. If you can't "QuickBMS" in archive, then most likely scenario is that the creator has update the archive and create a different link for it, look for the latest message on the forum or the first pages to ind new links for it.
You can download "QuickBMS" here: http://aluigi.altervista.org/quickbms.htm
Just like the script for 3DS Max, scripts for "QuickBMS" are different for different games, so you should look better in their descriptions.
Just like additional instrument to work with models in 3DS MAX you might also need to download a script called "Quadrangulate". All meshes, that you import in 3DS MAX will be divided in to triangles, This is okay for games that was optimized to use in Video Games. But if you planned to use this models for different purposes, for example, to render animation, then it will be much better for you if you divide models in rectangles. And exactly for this you might need this script. It's free, and you can download it here: http://www.scriptspot.com/3ds-max/scripts/quadrangulate
