Since 5.6, if you are executing offline Path Tracing rendering during runtime, it won’t finish the rendering, turning into a black screen at some point. Working perfectly fine in 5.5.

### What Type of Bug are you experiencing?

Rendering (Graphics / Niagara)

### Steps to Reproduce

Create a Path Tracing rendering task with the sample incluided in engine, for example: \Engine\Plugins\MovieScene\MovieRenderPipeline\Content\Blueprints

### Expected Result

Path Tracing rendering being showed in screen, progessing “cleaning” the image.

### Observed Result

Path Tracing being stopped and/or showing a black screen (in game, not in the whole computer).

5.8  
5.7
