    I have noticed that pretty much no one knows how this works and I decided to make a guide of my findings of getting the lighting preview to work.

    so first you of course start with the scene which you want a light preview of
    next of course you will click on the button that says camera and click on lighting preview

    now of course this won't work at first but there still is a couple simple things you have to do
    just then click on camera again and click on ray-traced preview
    finally click on camera again and click on lightmap grid.

    Then a window should open that when it renders will show you the lighting preview.

    I have no idea why this works but it does, it really gives a nice look to a map when you just don't have the time
    to compile it but you want to show it off a little

    Not even sure if this is relavant information but realized that pretty much no one had figured this out so, hey if you still want to show off a pretty lighting scene while mapping but don't want to compile this is a pretty quick and easy way to do so, doesn't look exactly like it does in game but I think it does good with some scenic shots.

    "EDIT: Actually, you don't even need to select lighting preview. Just going straight to ray-traced preview will bring up the window." Thanks for Da Spud Lord for finding this out

    Wow, thanks for this! The biggest caveat I can find so far is that sky lighting looks weird and inconsistent, and in some shots it looks like the engine just entirely forgot to include sky lighting at all. I also wish the preview window had a higher resolution. But still, this seems super useful.

    Also, it seems like you don't need to select 3D lightmap grid. Just select lighting preview, then ray-traced preview, and then the window will appear.

    EDIT: Actually, you don't even need to select lighting preview. Just going straight to ray-traced preview will bring up the window.

    Thanks! I more or less just posed this because everyone treated lighting preview as a completely broken feature even though it is only a mostly broken feature, thanks for finding out about the whole going straight to ray-traced though without even clicking the lighting preview, even if that is what is brought up... man hammer editor is weird.
