frame count exports the number of frames, and 100 frames is equivalent to exporting 5 seconds of light-effect time. Because the time to export each frame is long, the export time is much longer than the intuitive optical effect playback time public int screenwidth = 960; Not the use is temporarily useless, you want to be able to directly set the size of the screen (that is, the size of the light effect canvas) public int screenheight = 640; Public Vector3 cameraposition = Ve
