Files ending with a .wmb extension are model files. They can be opened with Bayonetta 2 wmb.bt, Bayonetta WiiU wmb.bt and Bayonetta wmb.bt.

These files contain vertexes, bone structure (with a bone map), materials information and meshes for a given model.

Bayonetta 1 Mesh Arrangement/Numbering

All .WMB files for player models follow the same mesh numbering. Meshes that are not used are replaced with dummy to keep the numbering consistent. Each mesh number has attributes that most costumes follow (e.g. Nun costume doesn't have Durga/Odette glow effects). The Default costume will be used in this example. This link contains pictures of all meshes and their respective batches.

Bayonetta 1 Bone Structure

It has to be noted that in Bayonetta several model share the same animations. For this to work, models need to share a common basic skeleton and motions need to be able to reference it. In model files, bones are numbered from 0 to bone_count - 1. Thus in order to have a common numbering between animation swappable model a translation table is provided in each model. Bone numbers inside a model will be called local bone indexes or local bone numbers, and bone numbers shared between models will be called global bone indexes or global bone numbers.

The mapping between the local and global bone numbers can be obtained, for a given model, by the get_bone_map.rb command.
