Custom Material Pass in UE5

Hello

In UE4 there is a Custom Material Pass in Composure Transform pass. In UE5 not. What would be the equivalent in UE5. The UE4 tutorials are out of date and can not figure this out.

I´m trying to make a texture/ material/ render target from a cinecamera view to a widget.

Have been struggling with this for weeks so any help would be appreciated:)

Yours, Ramses
