# Objective
- The `scene_viewer` example assumes the `animation` feature is enabled, which it is by default. However, animations may have a performance cost that is undesirable when testing performance, for example. Then it is useful to be able to disable the `animation` feature and one would still like the `scene_viewer` example to work.
## Solution
- Gate animation code in `scene_viewer` on the `animation` feature being enabled.
