A camera can be associated to exactly one render target at a moment. A render target can be associated to one or more cameras, hence one or more cameras can use the same render target as output target.
--- #### Render Target Swapping Once all cameras are finished with rendering their content onto a render target, the render target must be swapped. There are two options to ensure this: - Enable the "Enable Swapping" property of exactly one camera linked to the render target. In case of more cameras, take the camera with the highest sequence numbers, so only the last camera linked to a render target will trigger the swap of the render target buffers. - If no camera has "Enable Swapping" property enabled, the application must take care to swap the buffers during the render loop correctly.
In case no swapping is done, the display will remain black. In case more than one swapping is done during a render pass, the display will flicker.
--- #### Additional Info about Rendering This section explains the render loop performed by SCHost for the Scene Editor part of SceneComposer. For each frame, the following procedure is executed: Displays are cleared (all the render targets are cleared) - due to specific requirements. All cameras are rendered in the order specified by the camera property "Sequence Number". A camera is rendered only if it is explicitly enabled in the Render Targets panel. ##### Active Camera Rendering: - 3D: Active camera attached to scene render panel is about to be rendered. > If the camera has any ReflectionCamera children, they will be placed in a list along with the active camera. > The list is sorted considering the Sequence Number property of the cameras. > All the cameras in the list are rendered. > The scene render panel render target is swapped. - 2D: Active camera attached to scene render panel is rendered.
