Stat game and SpawnActor metrics

Hi all, stat game related question, using the screenshot from this reddit post as reference: https://www.reddit.com/r/unrealengine/comments/10db751/can_somebody_please_explain_stat_game_to_me/

  1. when I use stat game it shows the rows for SpawnActor and SpawnTime only some times - is there a toggle to switch them on/off?
  2. what does it mean when a row has not value displayed?
  3. in World Partition, when a new cell is loaded, are the corresponding actors created through actor spawning? If so I’d expect to see some value there, while I always get an empty row (when it shows up…)

Thanks!

Hello there @rickyviking!

For your first inquiry, there is no specific toggle for rows, as spawnactor and spawntime will show in stat game whenever an actor is present in the frame. If no actors are on screen, the row will dissapear, or show with no values at all.

On the second one, if a row appears with no values, it means that something on scene triggered that row at some point, but the current frame does not have this element, which results in empty values.

And for the last one, actors are spatially loaded with WP, they don’t go through spawnActor, since its a separated process. Which means, you won’t see values in spawnactor, even when actors are appearing in scene.

Thanks @brs-sebascova ,

that explains the reason why we have no values on the SpawnActor row, when it does appear, as our scene is World Partition based and all actors are either always loaded or spatially loaded.

The reason for the question is that we are looking for some metrics to investigate some World Partition stuttering behavior, as explained in this other question.

Thanks,
Riccardo
