To add a model to the shape browser just drag the .obj file inside the Shapes folder on the same directory of the executable file. Every time you open the shape Browser it will go trough all the new models and create cache files to accelerate the load next time it opens. If you have caches with multiple characters you should keep all the models separated on the shape Browser. For example, if you have a dog and a horse on the scene, don’t export the dog and the horse together to the shape browser, you should always export the models separated like: Horser_body, Horse_teeth… The software will figure it out which models you are trying to clone. The important thing is to keep the same point order you have in your application.
