My flames always look brighter than what's in the video (as if the smoke never appears in front of the flame). Is that because I'm using 2.78? https://drive.google.com/file/d/0B61Z1wMgyCh9TThUZmFGTHB6c0U/view?usp=sharing
Yeah, it looks like it's just a weird viewport quirk that happens sometimes. The shading will change a bit depending on what's selected, so that could be a part of it. It doesn't change the render at all though.
