Daily Unreal Column #55 - Freeze Rendering
When trying to inspect different rendering issues there is one console command that is invaluable.
Using FreezeRendering
console command allows to freeze the current state of rendering without freezing the entire editor or game. It allows you to keep playing the game like nothing happened. I personally used this command multiple times to investigate the culling system. Thanks to the fact that the game is not frozen, we can keep walking with our character in the game and look for things that should or shouldn’t be culled.

Take into account that this doesn't work with Nanite meshes. Its culling system uses a different method.
