Test the Forward Renderer in your PC VR projects with the 4.14 Preview

Hey!

I’m new to the VR world, and am trying to better understand the performance part of it. As a test, I use the standard VR Template Project (Startup Map) from Unreal Engine, without any changes…

I tried enabling Forward Rendering in UE 4.14, but for some reason, my world becomes much darker then.

Forward Shading On

If I add to the Starter Map (this map) a skybox, then the maps is light again. However, I am struggling to understand why this is not a problem in the Deferred Rendering example.

Any clue why Forward Shading is havind such effect on the lighting? Is there anything that I can do to fix this?

Thanks!
