iRay in Unity like in DAZ?

I have just tried the latest DAZ 3D Studio, it now uses iRay renderer, and the results where simply amazing.
After 5 minutes of rendering (and still not being finished), it already looks amazingly real:


I would like to ask if iRay uses some magic under the hood.
I always thought that a photorealistic render depends on the right shader, but after having seen this render, I am unsure again.

My ultimate question would be if we could get such a photorealistic render in Unity as well.

 

I take a dim view of "realism" anyway, but it'll never do to compare an offline raytracing renderer to one in a realtime game engine.

 

What is your suggestion then? Great shaders? Best normal maps?

 

This appears to be roughly along those lines.

Though I don't see why you couldn't call iRay from within Unity like any other C++ API.

5 minutes of rendering != 60 frames per second.

 

Possibly but that's a very subjective question. The two use fundamentally different styles of rendering with their own strengths and weaknesses. IRay is presumably a ray tracer, where virtually all games use triangle rasterisation.

 

I was only confused that - given enough time for calculations - photorealism can be achieved even from simple diffuse maps.
I always thought that photorealism was achieved by shine-through-areas and SSS which shaders and great spec, trans maps, etc. are responsible for.

 

If it's truly just a "simple diffuse map" then what is the "time for calculations" being used for?

 

Meh, you could make it look like that in Unreal without really trying too hard and you could make it look better if you did.. You could in Unity with a lot of faffing:

yes........?

Go see https://unity3d.com/showcase

Just like all "GAME" Engine, you can make photorealistic image with limitation. Baked lighting. Normal Maps to dodge the lowpoly problem. Tons of weird textures and shaders to fake a photorealistic detail. etc

 

This might be of interest.

 

Someone read this post on Hibernum company and make a render multi-pass to IRAY with Unity 3D.

Its very interesting, look all presentation, but on 22:00 minutes you will see NVIDIA IRAY with Unity Integration.

I hope in a near future the Hibernum company make this available to public on asset store !

The animation on demo scene dont have great materials, but on presentation will see some glass and other MDL materials running.

 

Can you believe, but I use Unity to render Stills for Archviz. This would be awesome.

 

I sent a e-mail to the company asking about this asset. If everybody that have interest, can make the difference to company start to make this available.

rebit,

I am also writing to "hibernum". Hope we can persuade them to make their work available via AssetStore

 

i wrote a month ago, no return.... :/

 

They are at a whole other level compared to game engines but then you'd expect that as I believe they are primarily used by Madison Avenue types professionally that have a bit more critical of an eye than a teenager looking for gore or sex.

Beard looks like it would make better cotton candy or clouds though it's much improved from the past.
