Options for motion vector rendering on the terrain.
| CameraMotionOnly | Use only camera movement to track motion for all SpeedTree models painted on the terrain. |
| PerObjectMotion | Use a specific pass to track motion for all SpeedTree models painted on the terrain. |
| ForceNoMotion | Don't track motion for SpeedTree models painted on the terrain. Note that models are still rendered in the object motion vector pass, so the CPU performance is similar to `Per Object Motion`. |
| InheritFromPrototype | For each SpeedTree model painted on the terrain, inherit the motion vector rendering mode from the import settings, instead of a terrain-global value. |
