説明

Render texture color pixels are memoryless when RenderTexture.antiAliasing is set to 2, 4 or 8.

Note that memoryless render textures are only supported on iOS/tvOS 10.0+ Metal. Render textures are read/write protected and stored in CPU or GPU memory on other platforms.

SA. RenderTexture.memorylessMode, RenderTexture.
