| cameraInstanceID | The InstanceID of the camera for which freeUnusedRenderingResources is being set. See Object.GetInstanceID. |
| freeUnusedRenderingResources | The value to set to this camera's freeUnusedRenderingResources flag. |
Defines whether Unity cleans up rendering resources for a given Camera during garbage collection.
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.
