I recorded how long it takes URC to revert a single file (in this case it was a spline). In other revision control systems its instant, so I wanted to bring it up. At the end of the video, me recording doesn’t allow the window to show, but as long as I stopped recording it showed.
@Wertandrew Thank you for your feedback. While I cannot guarantee a response, I can confirm that this has been forwarded to the appropriate team.
When reverting an actor (something that is placed in the world), some of the world data needs to be reloaded and re-initialized to reflect the change on disk for that actor in the viewport. The revert source control operation is quick (for example: try reverting a material from the ContentBrowser). However, the reloading of the world data is known to be a slow operation in large projects.
