Display normals and tangents at runtime

[quinx]

Is there a flag in Viewport Show Flags that can display the normals and tangents of a mesh? I want to visualize them the same way I would for a static mesh in the mesh editor.

I don’t know if this is what you want to achieve, but you can see the normals of the 3D objects in the scene by
Selecting ViewMode->BufferVisualization->WorldNormal. If you are not able to access this menu click on the drop down arrow and select Show Toolbar
