Monitoring Real-Time Path Tracer Progress and Retrieving Progress Bar Status in Unreal Engine

Hello fellow developers,

I’m currently working on a project where I enable the path tracer at runtime using the command “ShowFlag.PathTracing 1”. While the path tracer is running, there is a progress bar displayed at the bottom of the screen, indicating the progress of the rendering process. However, I’m facing difficulties in finding a way to retrieve the status of the progress bar.

I would like to know if there is a method or a way to access the current progress value of the path tracer or retrieve the status of the progress bar during runtime. Is there a specific function or variable that I should utilize to achieve this?

Being able to monitor the progress of the path tracer is essential for my project, as it would allow me to determine when the path tracer is completed or how far along it has progressed.

Thank you in advance for your support and assistance!

@Netzwerk3D I am afraid there is no way at the moment.



The requested functionality of


is fundamentally important.

Please implement these, should be very easy in code.

I have desired it many times, too!

Meanwhile I was playing around with saving pathtraced renders at runtime using MovieRenderQueue.
It´s quite simple and here we have an OnFinished - Event at least.
