各 LOD の Light Probe ライティングを有効にするブール値の配列を取得して設定します。
Billboard LOD のために True を指定するとバッチ処理をブレークし、パフォーマンスが低下する可能性があります。
This setting controls whether the SpeedTree materials use light probe rendering. Because light probe rendering comes with an increased performance cost, you may want to only enable it on the SpeedTree assets that are nearest to the player. You can use this feature to improve performance by disabling the effect on some of your less detailed LOD levels where the models are far enough away from the camera that the absence of this effect is not noticeable. The array length that you supply must match the number of LOD levels in your SpeedTree asset, and typically would have true values at the start, and false values at the end. For example, if your SpeedTree asset has three LOD levels, you might pass an array of [ true, true, false ] to enable light probe rendering on the first two LOD levels, but disable it on the third.
