This program is designed for importing game files (Geometry, textures, skeleton) and exporting them to *.smd, *.obj files. These files can be edited in 3D editors. After that, using Archangel, they can be re-exported into game files.
I have included various materials in the Archangel archive that may be useful to you. Documentation, plugins, programs for working with 3D models and animations.
