Advanced Preview Monitor (APM) is a powerful displaying interface that gives you the ability to preview your Engine scene in real-time right inside the Reality Hub user interface.
APM displays the video on the pin you selected.
To access it:
Move your mouse pointer over the Output pin of the Composite Passes node and right-click.
Go to Monitor and select Channel - A.
The screen symbol with letter on the Composite Passes node's Output pin indicates the which pin is currently monitored.
From left to right, APM buttons indicate the following features:
Safe Area: Borders for action-safe area and title-safe area. It always shows a 16:9 widescreen aspect ratio.
RGB: This feature allows you to display selected R, G, B, Y (Luminance) channels.
Zoom/Pan Reset: When you select the Split View, this button gets activated and resets your pan/zoom view into its default state.
A|B: Multiview allows you to check multiple outputs side by side.
A: Channel A (Single view)
B: Channel B (Single view)
A/B: Split View allows you to check and compare multiple outputs in a unified window. With the help of a splitter, you can check and compare two videos from a 360-degree angle.
Pop-out: This button allows you to popup APM as a new browser window. This function is helpful if you want to use APM in full-screen.
Advanced Preview Monitor is disabled in the Live Mode. For more details, please visit the Launcher Interface.
APM for Unreal Engine requires a different workflow. See Advanced Preview Monitor for Unreal Engine
