Epic Games' Tim Sweeney Explains Lack Of 'SVOGI' In Unreal Engine 4

DSOGaming writes: "Epic Games impressed gamers back in 2012 when it showcased its latest game engine, Unreal Engine 4, with its Global Illumination support. The Elemental Tech Demo was a beauty to behold, however its latest version – which ran on Sony’s PS4 – did not feature any of it. Naturally, a lot of PC gamers blamed consoles for not being powerful enough to run this end-all-be-all feature. And in an interview with GameTrailers, Epic Games’ Tim Sweeney decided to shed some light on that matter."

In context: "We created a CGI trailer that can't be reproduced on an affordable machine. And, by affordable, we mean sub $4000."

Epic still has a few kinks to work out, but i'm sure they will produce a nice 3rd party engine.

rocksteady probably will be using it to create the next batman.
which is on my (and i'm guessing a lot of other) buy on next-gen list

sure they are not the company as we kew them in there heyday but hell there not nobody either.

"In context: "We created a CGI trailer that can't be reproduced on an affordable machine. And, by affordable, we mean sub $4000.""

Actually, a better statement is:

"We created a CGI trailer that can't be reproduced on an *cheap and dumbed down* machine. And, by affordable, we mean sub $600 and by cheap we mean PS4."

Point being, the PS4 and most likely the next Xbox will be severely underpowered in the processing power department.

the article you would see that UE4 uses a technique similar to SVGOI, but not actual SVGOI like seen in the PC trailer. The only people who actually have Global Illumination in their engine is Crytek with Cryengine3. But even then even the only GI in the engine consists of the son only. The article barely mentions next gen consoles. It's more about lack of the lighting solution in UE4 period.

The Infiltrator demo did not have SVGOI in it which means ps4 and next xbox can achieve similar, if not the exact, same results. The CPU in games, mainly perform computation task such as physics. It in no way determines how games looks , as oppose to how the game runs.

For someone who suppose to be championing PC's, your lack of knowledge for something this basic is baffling.

I did read the article and in fact the article talks about the high cost of GI and therefore uses other techniques to get a "similar" look. This isn't much different than instead of costly raytracing and uses other techniques for light.

The article also mentions the high cost of real GI and no I said nothing specific to the CPU and merely mentioned processing power, which can mean CPU, GPU or both!

Crytek 3 only uses the "son" only, with one only one light bounce that is severely limited at this point.

That still doesn't change the fact that PC can barely do it, what do you think a dumbed down and cheap console can do?

Also, if you read my comment history, I'm actually a console champion, not PC. I'm just not console blind!

Doesn't matter how good ur tech is, if u don't have talented people around to use it, and that's why i see epic as a failure in the future and it saddens me because gears is one of my fav franchise's but that's the industry . I see crytek becoming the new epic and epic closing shop and only leasing there license instead of developing games all of there key talent didn't leave for no reason .

jetlian2101d ago

lol ha ha epic does more than make gears! it was and currently is the most used engine in gaming!

go whine as they are used by more companies this coming gen

Muerte24942101d ago

I wouldn't be so sure about that Bioware has already confirmed that they will be using DICE's new Frostbite3 engine for all future projects. This generation DICE and Crytek didn't get into consoles until two or three years after EPIC. Cryengine3, Frostbite3, and RED engine all look to be flexing their muscle this time around. Capcom's new engine and Luminous too.

My point is I think you're jumping the gun a little bit. While I agree that EPIC dominated this gen, I'm not sure it will be a continuing trend next gen. There are alot of companies just making their engines in house.

jetlian2101d ago (Edited 2101d ago )

Bioware,dice, and crytek have ties with EA. So yea they would use their own engines. CD project red used their own on witcher 2.

Same with capcom's MT framework this gen and SQ using there own. Only one changing in your post is bioware.

Im sure it could change this gen but I dont see it happening.Like you said it is early.The two demos infiltrator and Samaritan looked badass

mmike8552101d ago

Am I the only one who wasn't blown away by the UE4 Tech Demo?

shivvy242101d ago

Killzone SF and Battlefield 4 looks way better then the tech demo

Tei7772101d ago

yeah, it was a pretty underwhelming tech demo but then I guess thats because they aimed to demo something very achievable. I think the Infiltrator demo is the more ambitious," maybe we'll see games like this in a few years" tech demo. The elemental demo is what we will see developers achieving day one.

user76939582101d ago (Edited 2101d ago )

ok, a good excuse, but a excuse after all.
@mmike855 you are not alone.. A teach demo should have gameplay next time to impress me and not some "this is what out engine can do if your game is set in a small land and only has 2 brainless characters ..
I like more the faces tech demos if you want a non gameplay tech demo.. that's where you can see how much better the new tech is.

IMO, to a non technical gamer such as myself, the PS4 version looked pretty close to the PC version. There were some differences. The PS4 version didn't have some of the particle effects. But I thought the PS4's lighting was brighter and made it look more crisp. Just my opinion. The lighting was the biggest differences. To be significantly cheaper than a high end PC, PS4 still holds it's own. There's diffinately not as big of a gap as with PC and PS3. This is good for PC actually. How many PC games had to be built on scalable engines that could also work on inferior consoles? The next consoles should mean that PC can finally achieve what it's really capable of because it doesn't have to scale down so far. For example, Battlefield 3, Far Cry 3, etc.
