Nvidia announce new series of Grahpic Cards RTX-20 series with real time rendering.

Will we see a Daz Studio Iray integration of RTX in the future?

Here are some Vids of the upcoming tech:

I think it will happen but Daz won't directly decide it. The iray people will. From what I can tell, Daz doesn't make its renderers, It licenses ports of existing renderers. 3Delight is a licensed renderman renderer. Iray is a licensed PBR renderer. And Daz doesn't always get the best port. 3Delight is capable of more than what it does in Daz, but Daz is in love with Iray.

I have to say my preference is for the Iray render engine. It seems that you prefer 3Delight, any particular reasons why?

I use both. I like 3Delight because it's very fast and I can use texture preview to get an idea about my scene. Texture preview is fast and smooth. I see a lot of lag with iray preview. Shader controls are pretty good. Once 3Delight optimizes the images, the render time for added frames is blazing fast. 3Delight doesn't rev my cooling fans, and I have a better feel for the lighting model. There are drawbacks: No true HDR, no glows, no light-shedding surfaces, no radiosity or fancy lighting effects without extra effort. Iray does all that, but it places more stress on graphics hardware. I think 3Delight can do more of that, but not in Daz.

Hi Torquinox Have you been following the 3Delight threads at DAZ where some very clever people have created shaders to leverage all those features?

In my own experience I found that 3delight is fast, until you add any kind of realistic lighting to a scene, such as an Uber Environment lights then things can really slow down. Especially with transparency on things like hair. Portrait closeups with lots of hair can take what seems to be forever in my experience.

I'm not sure what kind of hardware you have, but I found my GTX 980 card flies through pretty much all Iray renders. You are right though that Iray is fairly heavy on hardware but no more so then running a modern game or a VR rig. 3Delight definitely isn't as picky with hardware and should run well on older tech or a CPU based system.

Out of curiosity, to see how things perform on my current system, I just did a quick test with a basic scene using Genesis 8, some clothing and hair each with optimised materials for both render engines applied.

Iray came in at 1 min 8 secs with an 8k Enviroment Map, while 3Delight came in at 4 Mins 30 secs (about 1 min 40 to optimise the images) with an Uber Enviro light and a single distant light. Iray using the CPU only came in around 5 mins.

I haven't touched the uber lights. That might be something to investigate.The real joy to 3Delight is the next render of the same scene. With no waiting for the images to optimize, the render pops a lot faster. From what you're saying, after I upgrade my system, Iray should be a lot more fun.

Those 2080 series cards START at $840 and go up from there. Ouch.

I'm going to see right now. Thanks for the headsup! :D

They are pretty close to the price of the last generation, maybe a little more I guess. A 1080ti card will still set you back around $1130, pre-order for the 2080ti is currently at $1200 on Amazon. When you compare specs especially in the Cuda Cores (Which will speed up Iray renders) you can see quite a big difference between the generations. With some reports that the 2080 card is twice as fast as the 1080 in certain situations, hopefully Iray rendering is one of them.

render speed is fast but it has a bit blur.color of skin is close to human .Teeth is white better than 3Delight.

I think your issues are more related to hardware than the render engines themselves. The Iray ported to DAZ is pretty much the same as the stand alone version and is even capable of being ported to Iray Server over a network, which frees up DAZ for authoring. I use two HP z820 workstaions with two Titan Xp in each, with one workstation running DAZ/Iray and the other workstation running Iray Server. Speeds are fast enough to use Iray in my viewport. So as is the case with any render engine hardware is key.

From what I have seen so far, Iray rendering speeds are doubled using RTX 2080 over say a pascal based Titan. Not sure yet what the results are with Quadro version of Turing GPU's.
