Systems and methods for utilizing living entities as markers for virtual content in an augmented reality environment are discussed herein. The virtual content may comprise objects, surfaces, textures, effects, and/or other content visibly manifested in views of the augmented reality environment. In some implementations, the virtual content may comprise an avatar and/or other full- or partial-body virtual content object depicted based on the living entity. A living entity and multiple linkage points for the living entity may be detected within the field of view of a user. Based on the arrangement of the linkage points, virtual content may be rendered and appear superimposed over or in conjunction with a view of the living entity in the augmented reality environment. In some implementations, the rendering of virtual content in the augmented reality environment may be triggered by the arrangement of the multiple linkage points for a given living entity.
