Hello
Several places in the program are reported that the both type of mesh files (wm for player models, am for other objects) is in GR2 (Granny v.2) files.
But, Granny viewer says that files is damaged.
Maybe is here some protection, maybe developers changed the format while programming. About textures, for example, program reported like .tga (targa) format, but all is in .dds.
The problem is also with the skeleton animations - its in havok 4.0.0. format, but most of it cannot be loaded to any editor that should support this format..
