The files that I'm using were located in the Shared.pak file. The animations are, I assume, the files located in folders with the "_ABC" suffix, going by how they're named (eg, "Humans_Hero_Male_ABC_Attack_1H_01.gr2"). When I run such a .GR2 through your converter, it gives me a standard .DAE file. I've tried importing these into both Blender and Maya after loading the associated character model and rig, but nothing seems to be added.
EDIT: I seem to have made some progress on this. I tried extracting an animation from an entirely different creature altogether (this time one of the Imp's attack animations), and oddly enough that seemed to read just fine in Blender (even if it didn't want to stick to the Imp's character model, despite the settings I applied in the armature options). I'm not sure what exactly is different about this animation file in particular, but after comparing it to the problematic ones in Notepad++, I did note that the <library_visual_scenes> section holds a considerable amount of data where the problematic ones have only
<library_visual_scenes>
<visual_scene id="DefaultVisualScene" name="unnamed" />
</library_visual_scenes>Whether or not that actually means anything I couldn't say, but it's the only structural difference I can find aside from apparently having been built in 3DS Max as opposed to Maya.
