• Reflections Only: The object becomes invisible, but appears in reflective surfaces around
it.
Reflections and Groups
In addition to choosing the reflections settings for individual objects, you can adjust the
settings for an entire group. Reflections settings for a group override the settings of
individual layers within the group. For example, if an individual object in a group was not
set to receive reflections, turning that setting on for the whole group will force the
individual object to receive them. Turning off the setting for the group allows the individual
objects’ settings to act as expected.
The Cast Reflections settings work differently. If the group is set to cast reflections,
individual objects’ reflections can still be turned off (or set to Reflections Only). However,
if the group is set to not cast reflections at all, individual objects will never cast a reflection,
regardless of their setting.
Disabling Reflections
Rendering reflections can significantly impact playback performance, so you may want
to temporarily disable all reflections to improve playback speed while working on other
aspects of your project.
