指定是否应渲染运动矢量(如果可能)。
设置后,该摄像机渲染另一个通道(在不透明效果之后,但在图像特效之前):首先渲染全屏通道,以便从摄像机移动重建屏幕空间运动,然后,任何移动对象都有一个自定义通道,用于渲染它们的对象特定运动。该缓冲区使用 RenderTextureFormat.RGHalf 格式,因此该功能仅在支持此格式的平台上有效。
运动矢量捕获对象从一帧到下一帧的每像素屏幕空间运动。使用此速度来重建先前位置,计算运动模糊的模糊,或者实现时间抗锯齿。
要访问生成的运动矢量,只需读取纹理采样器:任何不透明图像效果中的 sampler2D_half _CameraMotionVectorsTexture。
