| cameraInstanceID | The InstanceID of the camera being queried. See Object.GetInstanceID. |
bool
Returns true if all rendering resources for the given camera are saved regardless of usage. Returns false if garbage collection is allowed to free unused resources.
Each Camera has its own KeepUnusedRenderingResources setting, which is false by default. Unity uses this per-Camera setting in combination with the Terrain's overall KeepUnusedRenderingResources setting. If either setting is true, Unity preserves all rendering resources regardless of how long they've remained unused.
