I’m trying to get into the unreal engine 4.21 editor for the first time and I just tried to change the meshes from the test project “RealisticRendering”. When I select the couch for editing it, I correctly go to the editor but no tab “Mesh Editing” is shown (only “Toolbar”), so that I cannot edit any meshes.
It works for me on ue 4.23 Preview with Unreal Studio. Maybe you’re not using an Unreal Studio project. From the yellow box “The Static Mesh editing mode described on this page is currently only available in Unreal Studio Projects…”
