Syntax
class FFrameGrabber
Remarks
Class responsible for resolving render target data for a specific viewport in an efficient manner Internally, the class uses a fixed array of resolution surfaces, and dispatches rendering commands to resolve the viewport render target into a specific index into this array. This means we can resolve the render target data without having to wait, or flush rendering commands.
