Go to your level and open level blueprint and create this nodes
Inside commands string you can enter following commands to get the view that you want:
viewmode unlit
viewmode wireframe
viewmode lit
viewmode wireframe
viewmode lit_detaillighting
viewmode lightingonly
viewmode lightcomplexity
I couldn’t find one for the reflection, but here the link to the doc where you can find the info about different view modes,
Thanks,
