Datasmith grayed out

The plugin is grayed out in VR template? with version 4.19 previous versions are fine.

How do I turn it back on?

Thank you a

ok you have to convert it to Unreal Studio Project in the Plugin settings under Unreal Studio tab.

Where is the “Unreal Studio tab”?

It’s in Unreal Editor under Edit > Plugins > scroll down to ‘Unreal Studio’ tab on the left > you’ll see a tooltip on the bottom with a button to convert project to Unreal Studio

solved, thanks a lot!
