捕获屏幕截图和帧序列

Video Grabber is a UnigineEditor tool for high-quality capturing of screenshots and frame sequences. Frame sequences are captured in a special non-real-time mode, allowing to get any fixed FPS even on a low-end hardware. In comparison with traditional CPU-based offline rendering, this tool allows much faster rendering thanks to GPU acceleration.
