-#### Why is not it displayed properly in SceneView?
-
-SoftMask calculates the final alpha value based on the value of each channel of the soft mask buffer.
-The soft mask buffer is a buffer generated based on GameView's screen space.
-
-Since SceneView has a view matrix and a projection matrix independent of GameView, the SceneView's camera can not refer to the soft mask buffer properly.
-
-Therefore, in GameView, it is displayed properly. but in ScreenView, it is displayed like default Mask.
