Enlighten is an awesome technology. But there is really no price for a license or something else. A bit disappointing. Does anybody know if VXGI will be implemented in the Unreal Engine 4 till the end of the year? NVIDIA told that. But there is no statement from EPIC to this topic. For this reason I have no hope that this feature will be coming. Baking Lightmaps takes too much time.

Here's what they say about doors (dynamic objects)
Q: Can I do opening of doors and gates?
A: As discussed above authoring systems and scripting the exchange of bounce between systems depending on the door or gate will solve this in some cases.

Which isn't clear exactly what their solution is.

While cool, I don't like the limitations much.
I'd be happy getting the last little bits of what Lionhead has for LPV (I forget what it was, something about light injection or something to do with the sky?).Storyteller - An immersive VR audiobook player

Please anyone help me. I don't want to ask answerhub for now.
I wanted to mimic the feel of the video of Enlighten. So I started fiddling with LPV. I don't know if Lionhead solution is implemented or not and how to access and what is it about and how different it is from UE4 default LPV. I followed these tuorials:
https://wiki.unrealengine.com/Light_...ion_Volumes_GI
https://docs.unrealengine.com/latest...mes/index.html
And this video to make a dynamic sun to create the dynamic light for dynamic GI:
https://www.youtube.com/watch?v=Oni6TG2DXnk
I made coloured BSPs and I chnaged the time and colours and I got these results:

And I tried to do that in the same from the video aka Architecture by changing the Directional Light like in the tutorials and I got this: The sunlight going through the red curtain and diffusing reddish light almost like the video:
http://i.imgur.com/qiC6YMe.jpg
But when I tried to do the same in the map no light that has the flashlight tied to the player, I couldn't even find how to change its light like in the tutorial to make it behave like the video forcing it to diffuse red when I orineted the flashlight towards the curtains

Please help to set the flashlight to create dynamic GI using what is proposed within UE4( I hope the trick doesn't work only for directional lights like the sun otherwise we are doomed). Thanks

LPV can't produce results like Enlighten, the detail isn't there and it doesn't actually cast shadows with the secondary bounces.
In your case, the issue is that LPV isn't supported on spotlights, currently it's only supported with directional lights and emissive textures. And ultimately it's not going to give good results for interiors.

I don't work for Epic, as far as the stuff with Lionhead--LPV is their solution, the only thing that they have that isn't currently in UE4 is skylight injection(so that not all light comes from the directional light). That's it, the only thing thing they may add to LPV is cascades, right now you can only define a specific area size that uses LPV, which is bad for interiors because to get better quality you have to make the size smaller since the resolution is fitted to the size, but anything beyond that distance doesn't get any LPV and interiors often end up black from that, cascades would allow it to use a lower resolution area outside of the main area so that while it wouldn't be good quality, at least there would be some effect there.
But, even if you shrink the LPV size very small to see the quality it is still very poor quality. It will never be a very good dynamic GI solution. For UE4 the most likely fix is with Distance Field solutions, right now can do shadows and AO, they are looking into how they can use it to do 1 bounce GI and it would give much better results than LPV though still not as good as their original SVOGI solution or Nvidia's VXGI.
At the moment it looks like VXGI is the best solution, it gives quality results but performance is better than stuff like SVOGI

The only advantage Enlighten brings to the table is you can move lights about at free will when it's done it's geometry pre-cache.
As for LPV, it's fine for a quick cheap solution.. It looks great in CryEngine, we know it'll never be a real time photon mapping or RT solution..Last edited by ShadowKindGames; 10-31-2014, 01:25 AM.

That's pretty much what Enlighten does, what it's always done.. If you change a shader, it has to re-cluster the whole thing and if you move a static mesh it also has to re-compute the whole thing.

Originally posted by PLASTICA-MAN View PostOh I see. And what about the Lionhead solution you integrated? What does it consist in? I read it is a dynamic GI.
Anyway, for me, Enlighten seems cool but I imagine the licensing probably isn't attainable for hobbyists or small indie devs, and thus not too interesting. I'm more interested in solutions which don't involve proprietary plugins and email-to-ask licenses.Storyteller - An immersive VR audiobook player
