It’s important to not name the node 
                      
                        front
                       or 
                      
                        back
                      
                    
            To enable a Viewport in Unreal to be captured by SMODE you need to edit the nDisplay_InCamVFX_Config
            
                                Create a Node with the Ip Address of your server that will run Unreal,your node (windows) will need a custom output setting with the Type 
                    
                      Smode_metadata
                    
                     
                    
                                The Viewport needs to have a projection policy set to Camera with the ICVFXCamera selected
            
 
                    
                                the windows and Viewport resolution can be any resolution (it’s better to stick to standard resolutions)
            
                                (Here in this screenshot there is only one node but this depend on your setup for example you can have multiple node for when unreal is connected to the LED screens in a decentralized setup)
            
                                The node name is not important for now
            
                                If you need alpha you can setup the 
                    Unreal Key
                    Render a Unreal Key for Smode to use as Alpha Layer
