Getting cheap localized GI in Unreal Engine 4

I wanted to get up a video going over the localized GI system I built in UE4 as well as the new light probe system. None of these methods add any extra light actors of any kind, no point lights, spot lights, etc... They are all calculated through blueprint and rendered through a post process material.
Few facts:
Both of these systems are extremely good on performance and come at almost no cost.
Both the GI and Light Probes are calculated through a combination of blueprint, material collection parameters, and post process materials.
Lighting from both systems takes into account roughness, world normals, and Ambient Occlusion so their interaction with the environment feels will usually feel very natural and give correct directionality like real lighting.
Light probe system has a very low flat cost, doesn't matter how much of the world the lighting is effecting, how much overlap is happening, or how many are used, the fps cost will remain the same(Very low). This system also has the bonus of being able to light translucent objects/vfx at no extra cost and will effect them at infinite distances.
I hope to eventually get both of these systems up on the Unreal Marketplace at some point.

I would pay a lot for such a convenient system, simply amazing !

[@Xiox321]

Everyone who uses UE4 should know this. Great video!

[@guillem99]

How did you manage to light the scene using a post-process material? Could you recommend me some tutorials? Your work is amazing!

[@mhnoni]

That's a lot of work,a full system so yeah great job.

[@NicolasSilvaVasault]

very interesting trick, tho i suppose after nvidia came up with ray tracing technique for ue4, we might see real time gi on ue4 one day, but for now this sounds like the best option

[@itsmagnator]

Nice, any estimate for marketplace release?

[@awesomeniac]

It would be very useful for character flashlight

[@jkashaar]

Dude, this is really smart - nice work! :)

[@LittleBlue42]

I am very interested in this even at a beta stage. If there is a place to purchase this, I would be very interested. Thanks!

[@plasticZarathustra]

I would buy this if it was on the market place. Like actually.

[@flaydn919]

thats impressive !

[@carl14281]

I really hope you put this on gumroad, UE4 marketplace is slow as hell getting any updates

[@drumsterbaby]

Please add this to the market place

[@LucianoJacomeli]

best video using ue4 i really like to buy this! please put on gumroad or Marketplace

[@Hereson]

That's amazing!

[@Skythedragon]

Very nice!

[@domt9999]

"Quick video"... anyways love the videos

[@plorks445]

Nice work! On the marketplace?

[@musictaster9339]

Very cool! Do you plan to finish the first one (the scene capture based GI)? Cuz your latest video is only about the light probes. Cheers!

[@evilmrfrank]

I hope to still yes. It would probably be a separate release. I'd have to do some refactoring of the system to make it more widely usable first :)

[@musictaster9339]

@@evilmrfrank Hey, any news on that? I was thinking about creating something similar (1x1 capture for color, feed lineTrace hit location into material and use the locations for sphere-masked pseudo light postprocess) ... But that's probably only a tip of an iceberg, so maybe I'll wait for your already advanced system to be published :)

[@evilmrfrank]

@@musictaster9339 I still hope to at some point, just super swamped at work so will probably be a couple of months before I have the time unfortunately

[@plasticZarathustra]

Great video! Can you inform me about your pc specs? (I want to be a Unreal dev and looking for a pc that can run Ue4 efficiency)

[@flaydn919]

thats not hard. 8-16gb ram and an i7 4790k or i5 4690k is way good enough

[@evilmrfrank]

I have an intel I7 4960x, Nvidia 980 TI and 32 Gigs of ram, you do not need anywhere near that to work in UE4. It's only at more complex environments/work that you will need something more powerful. My computer does struggle with some of the more demanding work I do still but most ppl don't even need this powerful of a computer.

[@plasticZarathustra]

evilmrfrank Okay, thanks (:

[@plasticZarathustra]

Flaydn it’s because have a shit computer though that can run unity at 30 FPS

[@josephlemons]

Will this be released on the marketplace?

[@evilmrfrank]

I hope to at some point yes, will probably be a few months out though.

[@jean-pierrekey2301]

Did you ever get the localised GI system on the marketplace?

[@ErvinJesse]

I want to buy this
