⚠️ For versions of blender prior to 3.5, you may encounter the error messageFailed to load Mitsuba package after installing the dependencies via pip. In order to fix that, you need to run blender with the--python-use-system-env flag in order for it to correctly pick up the dependencies. In order to do so, find the path to the blender executable, and in a command prompt run:

<path_to_blender> --python-use-sytem-env
