On last stream Daniel Wright said that (in his personal opinion), distance field based GI is the best shot at having dynamic GI in UE4. Though I have some doubts about it. Like: 1. It will probabaly be only one bounce. Even if technique could in theory support more then… 2. We are limited on distance at which distance fields can be traced, so it limits us to single bounce. So we would need at least two more complimentary GI techniques like: SSDO for screen space GI (small range) And something for more large scale GI, that will reach beyond 3 meters. In anycase it’s hard to say where exactly issues with precomputing GI with enlighten lies, as Geomerics do not share any details how their tech work. ---

I’m wondering why there are no real informations ??? They just throw out the demo “which is really cool” but what about some informations? Release? Price? techical informations ? maybe even free integration to UE4 ? etc… etc… I just checked Enlightens webpage, there are also 0 informations… I’m curious about the twitch stream tomorrow, hopefully they will bring us some informations… ---

> [@](#): > > In anycase it’s hard to say where exactly issues with precomputing GI with enlighten lies, as Geomerics do not share any details how their tech work. The preprocessing is where it has to make low-detail meshes of all of the level geometry, it does it automatically. In Unity there are currently other limitations based on things like light types that they haven’t implemented yet, the biggest limitation to me is that it doesn’t work with moving objects. For the most part that’s not a problem for people, but for instance that’s a very big problem for doors, where it can use a probe to fake the lighting of the area but the lighting inside and outside the door can be extremely different and then the probe effect doesn’t work since it doesn’t take that into account. ---

It’s unclear what all they can do with dynamic objects, it definitely can’t render fully dynamic GI like it does with everything else. Currently it doesn’t do any of those things, it just uses a dynamically updating probe for those objects, just like UE4 does already. ---

Enlighten is an 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. ---

For this reason I have no hope that this feature will be coming. Baking Lightmaps takes too much time. Epic does not want to integrate anything that only works on one GPU brand, so if it only works on Nvidia graphics cards then they aren’t interested in adding it. They said it’s something they would consider if it has enough platform support, but there’s other things they’d have to work out with Nvidia like how the code would need to be in the available source and stuff like that. At the moment it doesn’t seem like they’re particularly interested in pursuing it. ---

It is, but it’s not using GI, it’s using regular light probes. ---

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?). ---

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.

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. ---
