Unreal Engine 4 Emissive from VXGI
Emissive? Lightspeed? We’re in a hurry! Time is money! Quick, rush-rush, faster! Not done yet? Get going already! But what if we run into an obstacle? Lets say a scene we don’t fancy that much? Unavoidable at times. Still, we can either dig in deep or decide to get rid of it as fast as possible.
It just so happens I came across such a scene myself recently. A while ago, Evermotion published a whole bunch of ready-made examples for Unreal Engine 4. Now I’ve come to know Evermotion’ example scenes as kind of a mixed bag. Usually there’s some good, some mediocre and some bad, all nicely packed together. This Unreal Engine bundle was no exception. You can see they’ve tried, but ultimately it all feels kinda uninspired. If there’s a theme or a philosophy to these scenes (other than selling stuff), please do enlighten me cause I couldn’t find it. Right, with that small rant out of the way, what are we supposed to do with examples like the above? Not much of course. We can extract some assets and that’s pretty much it. Or is it? Hmm. I suppose we could use it for a quick demo on how to get rid of Architectural scenes you don’t particularly like yourself the quick and easy/dirty way 🙂
Enter VXGI at Lightspeed
If you’re not too picky and you won’t end up with a headache over certain limitations, this might be a really nice way of ditching whilst cashing. Ok, we have our content. Now the lighting right? This can take ages. Not this time! We just wrap things in a Skysphere, put a emissive material on it, enable VXGI and voilà, we’re done. Really? Well, you can still tweak some settings and find cool camera angles but yeah, in essence we’re done. No direct light, no Skylight, nothing. Just VXGI doing its magic with some simple emittance voxels. Think of it as a Dome Light with benefits. You won’t win the next CG award but hey, at least you saved some precious time to work on that project you do enjoy!
The good and the bad
- Ultra quick method for lighting your scene
- Minimalistic yet robust base lighting
- Ambient light only
- Restricted look for materials
VXGI with only emissive (ON/OFF)

No idea what the above was about?
Just ask away in the comment section below and I’ll try to answer to the best of my abilities (which are very limited).
