First let me say you did a great job so far! I made similar findings back in the days. I only never tried to code something- kudos to you for your hard work!
I am not sure how I did it ages ago, but I had several tools that could show me the Grim Fandango Demo models- and some could export it to a format I could re-import into my 3dsmax. I had to put on the maps too, you know about it. Luckily it wasn't a big puzzle with all objects on one point, but in position like it should be
Here is a small result from a long long time ago
After reading your post some days ago, I was wondering if you could grab the ingame models with a 3d capture ripper like 3dvia printscreen - http://www.3dvia.com/blog/software/3...a-printscreen/
I know its not the direct way but it usually gets the models with textures already on the objects. It can become helpy, especially if you want to rig the models and animate them later.
I am gonna try to "printscreen" the Grim Models in the full version, just as a test. Still, your work is very appreciated
Keep up the good work man
Edit: Doesn't work with 3dvia printscreen.. ah well
