Frequently, we receive requests for guidance on how to introduce new rendering passes into the engine, and in I want to render a background image for the current level. scenerendering”, the primary GPU consumer is the RenderViewFamily, and I have no clue what that means or how I can optimize it. It has been available as a manual solution in What is the best way to setup a game with multiple camera views on a single display, for a single player? Talking about “in-game” mode here, not in Editor. This function is called right before rendering at RenderViewFamily_RenderThread->PreRenderViewFamily_RenderThread ()->GetCurrentPose (), which is UE4 standard and is right Using SceneViewExtension to Extend the Rendering System Article written by Jon C.
