New Virtual Production Project in 5.4 wont open XR Virtual Scouting

Development Pipeline & Plugins

Starting a new Virtual Production project after the 5.4.2 update breaks the XR Virtual Scouting tool.

I kept getting the error, “Unable to Initialize XR Creative Mode " r.postProcessing.propagateAlpha must be set to 0 (requires and engine restart)”

I entered the console command and restarted, and it was still broken. I tried putting the command in the ini and still broken.

Does anyone know a workaround for this?

I submitted a bug report since these tools were designed specifically for Virtual Production. So for them to be enabled in the project by default and completely unusable doesn’t make sense. But we don’t have time on the project to wait for the bug to be fixed so any help would be greatly appreciated.

Update: This happens even in a blank project

I had the same issue as you, I fixed it doing this

Add to the DefaultEngine.ini the following code at the end:

[/Script/Engine.RendererSettings]
r.PostProcessing.PropagateAlpha=0
