Reversing a 3d model I want to know how to reverse a 3d model,for example some guys develop scripts and tools to extract 3d models from video games and then convert them to obj and stuff.I have no knowledge in these things apart from making edits using blender.
So i wanna know where do i start to learn 3d model reversing.
Your question is a bit broad. You would need to know the file format, and create an importer for this format in Blender. As an example: Starting with a documentation of the .mx format I created a script to import the models of an old game called forsaken. The source and links to the documentation are linked here: 

Is there a way to import .mx or .mxa files?
