Most characters share the same actors (Posette based characters do not have buttocks or upNeck actors). This means that almost any pose will work on almost any character to some extent with respect to rotation channels. Some adjustment may be necessary due to the diffring proportions of diffrent characters. Morph data (such as facial expressions) can be included in pose files, and wether this will work with a particular character can depend on the base geometry file, and the channels in the particular cr2. MAT poses depend on the UV mapping of the base geometry.
