Limit recursive reflections
When a reflective object (layer or group) is reflected in another object, the first object can be seen in the reflection, potentially causing an endless repetition of reflections. Motion limits the number of reflective bounces that can occur in a scene, preserving performance and preventing the viewer from getting lost in infinity. The number of allowed reflections is set per project.
Limit the number of recursive reflections in a project
Choose Edit > Project Properties (or press Command-J).
The Properties Inspector for the project opens.
In the Reflections section, adjust the Maximum Bounces slider.
