Vary Animation
if we want compare vray-rt and Ue4
so what is what is advantages and disadvantages of UE4 ?
which one is better in quality and result ?
which one is better in rendering time ?
also i see trees are static in vary !
Are you seriously trying to compare a fully featured pre-renderer with a real time render game engine? It’s like comparing apples and oranges … sure they are both fruit/food but they can be used for vastly different things. If you are just looking for a pre-render like that Vray animation then go right ahead and use it, UE4 brings different things to the table as it’s mostly real time/interactive and also a game engine.
thanks for answer
my field is architecture
i want compare ue4 and vray-rt only in Archviz ]
in archviz i need only animation output between 2 or 5 miniutes
so both vray-rt and ue4 have this abality
i know there is lots of differences
but the question is whith one is better for archviz ?
you can see this video - and compare with other topics video
UE4 is realtime and can be interactive, VRay is static. Which one is better is subjective to what you need and your skillset.
UE4 can be used to make animations much more quickly than rendering in Vray, it can also be used to make an interactive application. However, the quality will not be as high as what you get with Vray, but for a lot of people that is sufficient.
For those that have the time to spend you can also set up Nvidia VXGI to do fully dynamic lighting which can make things in UE4 even faster.
i need only a short animation between 2 or 5 minutes
both of them have AAA quality
in vray we dont need lightmaps !
but which one is faster ? with same hardware ?
in VXGI we dont need build lighting ?
all lighting prosess will solve by gtx970 or something like that in realtime ?
Yes, VXGI is dynamic GI, not as high quality as baked lighting but is very fast.
Here’s the thread about it: NVIDIA GameWorks Integration - General Discussion - Unreal Engine Forums
It requires downloading UE4 source code and VXGI branch from Nvidia and compiling the code yourself.
thanks for information
personally i like vray quality
but static trees are bad !
3ds max have lots of plugins that are working with vray
=====
i will continue UE4 because its amazing For me and my Needs
It’s very possible to have animated trees with vray. Check out plugins like itoo forest pack for example.
Vray / corona will give much better results than unreal of course. Perfect g.i, perfect reflections/refractions. With unreal we fake everything, or close to.
Depends on how photoreal you need your stuff to be! For rendering a 5 mins animation with vray you need a renderfarm tho, not with unreal. That’s the main selling point, for me at least.
with one i7 cpu like6700k ] how many hour it take to render 2 minutes animation first post scene ] ?
also i think vray-rt is much faster than Vray ?!
Vray-rt, afaik, isn’t much faster than vray cpu. It’s just different.
For the render time it depends on the scene complexity. If you need 3 hours to have a noise-free image… then a 2 mins animation @ 24 fps is 2880 frames that you need to render. Do you see why you need a render farm?
Heck, even if you could render each frame in 5 mins, it’s still 240h of rendering.
With real-time you can record a video in 60 fps instantly. The tradeoff is realism.
Heartlessphil covered everything. Vray/Corona (which I would recommend) will give you a love more accurate results, but that comes with long render times, maybe not so much Vray-RT, I haven’t tried it out in ages. There’s a lot to factor in though. I personally like the PBR workflow in UE4 with Substance Designer, but I know a lot of people like VRays material editor better.
It’s such a hard question to answer because it all comes down to personal preference.
Thing is that in the architecture industry there are TONS of assets/materials, etc made for vray. Everything imaginable has been done for vray. It’s going to be the easier workflow for a long while!
One thing to consider is vray and corona comes with denoiser now. Could reduce render time by a significant margin but I have not tried it yet.
You’re lucky if you can get a Vray render to the 10 minute render time, so if you want to do animations then UE4 is a great option, even with building lighting. VrayRT isn’t generally faster since it has to clear up noise which can take a while.
thanks for all the answers
another vray video
i dont think this scene is impossible in ue4
another vray video
Probably possible but would require a lot more work.
The closest thing that ‘‘will’’ reunite real-time rendering and gpu offline raytracing is the announced Octane render plugin for ue4. Don’t hold your breathe tho because we could wait for a long time before we can use it.
By the way, Octane Render is a more complete gpu renderer than vray. It’s quite powerful. Have a look at F-storm too, it’s in beta and it’s free for now. It’s , imho, the corona of gpu renderer. Very easy to setup.
Another great example of Corona rendering vs unreal rendering of the same scene, by rafael from ue4arch.
Barcelona pavilion renderings made with Corona https://corona-renderer.com/forum/index.php/topic,13023.0.html
Barcelona pavilion movie made with ue4
For the untrained eye, I’d say the ue4 version is as good as the corona version.
But of course, corona have better reflections and refractions. Some corona shots looks like real photos!
Ok I am in arch vis too using vray. Vray is slow and painful if you dont have renderfarm, constantly updating your processor and software. Vray give you realism but you lost too much time on that, UE is real time, and if you take that time is money, UE all the way. I think future is in real time rendering. Everyday they update and bring some new processors on market so rendering time is dropping and quality is rising, so my opinion with UT and his almost realistic look you cant miss it, it has enough quality for clients that doesnt have vision.
’‘it has enough quality for clients that doesnt have vision’'
It kinda sucks to work on bad projects for clients that sucks, no? If I had the choice between doing 1 high end viz with vray vs 10 average viz with ue4, I’d choose vray! You gotta enjoy your craft man!
But hopefully real-time continue to improve because the workflow is just way more fun than with offline renderer.
By the way try Corona. Imo it blows vray out of the water for architecture 
And their interactive preview renderer is almost like having a real-time preview hehe!
