Disable one file per actor

Hi, that’s pretty much it,

How to disable One file per actor on new projects on UE5?

I know is a very powerful and useful addition to previous workflows and teamwork, but sometimes I’m working alone or within a small team and I find myself pushing tons of changes to files in Perforce/GitLFS changelists, making them harder to read/control.

I just want to know how to disable it when a project doesn’t need to have it. Or maybe to have it only for some levels and not for others.

Thanks.

Hello Linqen, thank you for posting your question.

To disable One File per Actor:
From the main menu, go to Edit > Editor Preferences.
From the sidebar, select Experimental.
Locate the Tools section and enable the check box for One File Per Actor.

You can enable it on a per level basis but from what I can tell, you’d need OFPA active.

If you would like to learn more, here is the documentation on OPFA.

I hope this helps you.

Thank you very much for your answer,

Thanks to your solution, I found what was my mistake and misunderstanding,

My issue was with World Partition. The Third Person template starts with a map with it enabled, having one file per actor and using ExternalActors and ExternalObjects.

And because I duplicated that map, the feature was being enabled in my other maps as well. After researching and understanding that, I found that there is a tool that transforms a normal level to World Partition, but by default, if you create a new one, it will be a normal level.

Again, thanks for your support :slight_smile:

The tool in question didn’t exist for me, however I was able to disable External Actors by first disabling World Partition via the World Outliner, then just uncheck the External Actors checkbox from the World Outliner as well.
