Since the iray trial does not allow you to render. I am wondering how long it takes to render 1 frame in the iray plugin. This will vary widely by hardware and scene, but how does it compare to daz studio?

A "DAZ Iray render" and an "iClone Iray render" will have similar rendering times... provided the scenes are actually similar.

For me, I "budget" 2 minutes per image, ranging from 1 to 3 minutes pre frame.

It all depends on what quality you need, the specifics of the scene, and what "shortcuts" you might want to take. For example, do you really need "caustics" turned on?

If the trial doesn't allow you to render at all (not even with a water mark? That's lame), another option is the BUY the plug-in and TEST IT EXTENSIVELY FOR A WEEK. Reallusion DOES HONOR their RETURN POLICY. So you have a 14-day window in which to get a refund if it's not going to work for you.

To me, the plug-in was worthwhile as an "educational" learning opportunity in addition to whatever actual use I might get, even though rendering even a 10-minute video in Iray is something I will probably not do anytime in the next couple of years.

Hi, I don't use daz studio but with my machine (you see the spec in my profil) with the minimum parameters who are okay for me, and for the result who is okay for me (not for everybody) 15 s of animation takes 2H to 2H30

Im just rendering a Picture about 20 Minutes on an Rtx2090 Plus. I just builded a new Pc, and im a little bit afraid a Scene with 800 rames need Weeks

oh, well... already thought i am doing something wrong... rendering with a "slightly powerful" machine... rtx 3090, amd ryzen 9 5950X, 64 GB ram and rendering 200 frames still takes like 10 hours?... thats a little disappointing
i really like the results, but this means, i cant really use my computer for a couple days, if i want to render a scene of a few minutes.... probably should go with lesser settings

How many iterations have you set it to?

By using a lower number and then applying denoising you should get more reasonable render times. The hope is that Omniverse will be faster.

Also, I'm not sure if the renderer makes use of RTX optimization. It doesn't seem to get updated really.

Did you ever see any improvement with this? My setup is similar to yours, I've got a 3090rtx and a 5950. Rendering a single frame takes an insane amount of time but I'm new to rendering in iRay so I didn't know what to expect.

I bought the iRay rendering package because it looked so much better than the default. However, I create video content which require massive numbers of rendered images (30 per second) and iRay was WAY TOO SLOW for that. If you only need static images, it might be a great tool. For video, I would not recommend it.
That said, Reallusion is a good company that honors its return policies. As was previously mentioned you can buy it, test it for yourself and keep it if it meets your needs.

Let us know how it goes!

as a rule of thumb for all ray tracing engines - the more shadows you have, the longer the render takes. This is why low poly meshes render the fastest, less faces means less shadows to calculate - and also why it's a big deal for real time rendering. In iclone you don't have to worry about it as much, because iclone doesn't ray trace calculated shadows, more like a generic blocking of light - but it still bogs down with large textures and meshes being loaded to ram.

Moral of this post - the lower the polycount, the faster it is to render, and this is where great texturing shines as it keeps the detail in the textures / normal and bump maps without requiring a greater poly- face count from the mesh.

IRay is a dumb , brute force path tracer that was created to sell NIVIDIA hardware to the Arch vis industry.

It comes free with Daz studio and 99% of the Daz user base are still portrait artists, NOT animators.

It does not even have motion blur

I tried to warn the Iclone user base that Iray was not a render engine for animated film production but many seemed to believe that Reallusion would magically convert it to a “realtime” engine.

Of course if you need high quality still images its quite useful

Its all Moot now as you have Both the UE5 live link as well as the omniverse

and the improved engine coming next month in IC8.

As for animation, ,let IRay take its place, along side Indigo, in the rubbish bin of Iclone history.

Looks like whatever defaults I went with are wrong for iRay. At current speed 1 minute of HD footage will take 18 hours with a decent machine. This iss an RTX 3080, Ryzen 5950x 13core - 32 thread 128GB and on SSD if that makes a difference.

Apart from advanced tricks from YouTube power users the general tip is to use less iterations .
I use around 245 iterations and denoising from 244nand 720p video.

Still frame per seconds is too much.
For me native renderer with lighting from CC is very good but i use 3x3 super sampling and full screen render.

Iray still looks best but when for me at the end I am going to upload to YouTube then speed matters most.

Just google iray and Iclone and you will.find more advanced techniques which further reduce time.

Also make sure CPU is unchecked and only gpu is used for iray rendering.

In it's current form Iray isn't really ideally designed to work well with animation. It's primary use is for still images...although some have persevered and completed very shot animated clips.
