Setup:

(Example images included in purchase) Add prefab to scene. Parent fishnet's armature alongside avatar's (where body mesh and such are located). Assign the parent constraint on each fishnet bone to their corresponding Rexouium bone (Bone "Bell Corrective's" constraint is assigned to the Head bone). Optionally choose which variants you want to wear, and delete the unneeded meshes. Add needed parameters/layers to your Rex, then use the provided on/off animations to create on/off toggles, disable write defaults on the animations in the layers! Finally add the menu, modify it to only include what you desire, add it to your Rex's menus, and assign each toggle their corresponding parameter. Replace the default breathing and corrective animations with the provided animations, correctives especially important! Upload, test, and inevitably troubleshoot!
