Systems and methods are provided for generating, selecting, modifying and/or otherwise configuring occluder(s) used in mixed-reality environments. Pose information of a trackable device worn or carried by a user is determined. Based on that pose information, an assumption regarding the user's own pose is determined. An occluder is then configured in a manner to correspond to the assumed pose of the user for use in the mixed-reality environment. By generating the occluder in this manner, improved battery life by the trackable device can be achieved relative to conventional systems that rely entirely on iterative scanning of the user's body to determine body position.
