•
No: The object is ignored by reflective surfaces.
•
Reflection Only: The object becomes invisible, but appears in reflective surfaces around it.
Reflections and groups
In addition to choosing reflection settings for individual objects, you can adjust settings for
an entire group. Reflection settings for a group override the settings of individual layers in the
group. For example, if an object in a group is not set to receive reflections, turning that setting
on for the whole group forces the individual object to receive them. Turning off the setting for
the group allows the objects’ settings to act as expected.
Cast Reflection settings work differently. If the group is set to cast reflections, individual objects’
reflections can still be turned off (or set to Reflection Only). However, if the group is set to not
cast reflections at all, individual objects never cast a reflection, regardless of their setting.
Disable reflections
Rendering reflections can significantly impact playback performance. You can temporarily disable
reflections to improve playback speed while working on other aspects of your project.
