I know about 3Delight and Iray render modes.
But I came across this new rendering plugin in the DAZ Shop called Reality.
https://www.daz3d.com/reality-4-daz-studio-edition
I'm a bit confused as to what exactly it is exactly...
My guess is that Reality uses the LuxRender mode instead of Iray? It boasts up to 20 times faster CPU rendering with seamless integration of LuxRender new rendering modes.
Does this mean that if I purchase this Reality plug-in my renders will speed up by 20 times?
I don't want to spend $49.95 without knowing what I'm getting into.

Reality is a plugin to integrate LuxRender render engine and Daz Studio, so you can render with Lux instead of Iray or 3DL.
As for the “20 times faster” it means that Lux in GPU mode is 20 times faster than using Lux in CPU mode, not 20 times faster than Iray for example.
Thank you Leana!
If you don’t have a Nvidia card it could be 20x faster though
This is why I keep gazing longingly at Reality. I bought my video card before I started working with Daz, before I knew what Iray is or had any idea what a CUDA core does.
The issue with Luxrender is you will have to set all your own shaders. The results can be fabulous but the setup can take literal days.
I have a Nvidia card. Have no idea what a CUDA core is.
Maybe DAZ Studio will incorporate LUXrender one day as part of the render options so you won't need a plug in?
For now, I'm happy with Iray. It's pretty damn realistic. I think it's much more realistic than Firefly and 3Delight. And I like how it renders the full scene fairly quickly, even though a complete render can take hours. You can abort early and still have a descent looking render.
My wishlist is to get faster, more responsive Iray viewport previews. It's really cumbersome.
Technically there is no such thing as a CUDA core. CUDA is actually two seperate things. The first is parallel processing pipelines in each of an Nvidia GPU's SM's (Streaming Multiprocessors) these pipelines also get called shader processors at times.. The number of such pipelines per SM varies with the GPU microarchitecture. The second is an API to let programmers work directly with that parallel processing capability. This is what lets Nvidia's GPU get used not just for graphics but for general compute needs as well.
This capability of running the same several thousand instances of the same process at the same time is what makes GPU's, AMD's GPU's have a similiar but incompatible counterpart, so good at things like rendering or AI.
Thanks Ken. Good information! Is there a good gaming PC you would recommend that has all the bells and whistles for Iray renders?
I purchased an Alienware - Aurora 7 Gaming Desktop, but my next one I'd like to be more powerful maybe.
If you must buy a pre built, you'll always pay more and you're likely getting substandard parts, pay attention to what model of graphics card is listed, You want a GTX or RTX with more VRAM (the more VRAM, generally speaking, equals more CUDA, the next most important thing is how much RAM the system has. You'll need at least twice as much RAM as VRAM (this shouldn't be much of an issue usually.
Just do not buy anything with a Radeon GPU. That's the AMD GPU brand and no matter how good will not render Iray.
Exactly this!
I really like the results you can achieve with Iray but the Iray preview slows down any creative process to a crawl.
I´ve got 2 RTX cards running in my rig and while the preview itself is working well enough as long as your scene is not that big, it literally takes ages to switch between texture and iray preview.
On top of that i assume even the upcoming integration of propper RTX support won´t change anything about this issue.
I cannot imagine a way that Iray preview can be very fast. It has to initialize the Iray engine and load the scene and start rendering. That's a "slow" process.
I have a 1080ti and 2070 and adding the 2070 really didnm't have much if any effect on how fast Iray viewport starts rendering. If/when RTX support is added it will make rendering faster so while it won't make the start of showing an image in the Iray viewport faster the quality of the image should improve faster.
M-C I agree! Switching between Texture and Iray Preview can take ages. I don't understand why it cannot be more responsive. If you try to move something in the scene or pan around it can get stuck even longer.
So I try not to use Iray preview until the last part of the scene building ... but if you then have to switch back to Texture Preview because you forgot something or want to change other scene items, that's where it starts to get really frustrating.
That's good to know about RTX. Thanks.
Reality uses the old Luxrender and seems pretty much dead as it didn't get any update for a long time. It didn't switch to the new Luxcore Render engine
And as some have said, you'll have to setup all the shaders
The problem when switching between texture and iray is that data must be transfered to the GPU and the speed depends on your hardware config. The best you can have is if your GPU is on a PCIe 3.0 slot at 16x.
A workaroung to the problem is to open an Auxiliary Viewport that you put in Iray Preview and keep the other Viewport in Texture mode
This way you can almost instantaneously switch between the two view mode
I will try that. Thanks Takeo.
