[REQUEST] Ambient Light

Hello. I’ve been trying to get simple flat lighting in my project for the last hour. Simple right?
Turns out all I need to do is download Photoshop at the small cost of $40, create a cubemap dds specifically tailored to my needs (this cannot be changed in UE4), add a post-processing effect, and use an ambient cubemap. But seeing as I don’t have photoshop, I guess that idea’s out the window.

Of course, silly me, I could use skylight. Well, actually, no I can’t, because it doesn’t work without atmospheric fog.

Why is something so simple missing from the editor?
