I have to say I'm disappointed in this, both in the decision and in the way it was done.

@0Calvin: I wouldn't hold my breath.

We have had two attempts now to integrate a ray-tracing renderer and while Iray is not bad, there are known limitations that have never been addressed. Also, once introduced, Iray wasn't further updated to keep up with newer developments. 

Time and again, we see a promising third-party tool or asset introduced (I'm thinking about PopcornFX, SpeedTrees), which then never gets updated to the latest version available. This is my one major gripe with RL, although I also realize that the development  team is relatively small.

So for now, our best bet is that the workflow with Omniverse is improved, as that is a solution that has continued development by Nvidia.


Yes, I'm not holding my breath, there. I guess there is also the Blender pipeline. Working in Blender makes me break out in a rash, though.

Daz recently announced that the next version of Daz studio will export to omniverse. so it is likely that they too will cease Iray support at some point.
Iray is a DUMB brute force path tracer originally designed for the Architectural/product visualization industry as a loss leader product to sell graphic cards.
It was never suitable for an animation software like Iclone
,particularly before RTX technology was widely available .

The speed of Omniverse is pretty impressive if you have the required hardware.

Unfortunately, the Omniverse workflow is a clunky mess with so many limitations right now that this is just not a viable alternative to the Iray plugin. I realize that most iClone users seem to be OK with the realtime renderer, which is definitely not bad, but it is still no substitute for a good ray-tracing engine. I hope we eventually get another tightly-integrated ray-tracing render option in the future because when/if my Iray plugin stops working, this program will become nearly useless to me.

I would have loved it if Reallusion had developed the Realtime auto-disable/enable visual states of content that the camera can and can't see using frustum + occlusion culling technology rather than only relying on clipping the view distance. The visual states could be baked into the timeline for faster playback I provided free code examples to the Development to help expedite this so that everyone can experience up to 3X faster Iray and Native Renders, and another 2-3 times faster when the stage is reduced in size to thumbnail and the iclone system priority in the taskbar is set to high. Using this setup could be superior to the speed of Omniverse right now but could complement Omniverse if iClone projects can be exported to omniverse with the visual states of all the assets baked into the USD file, if not we'd need a script. 

Game engines currently use these culling techniques, I wish Reallusion would take advantage of it. A couple downsides pushing users to rely on the omniverse for rendering is that it requires RTX cards, I currently use several (6) GTX 970s, an RTX 2080 ti, now a RTX 4090 24GB! and wish I could utilize them all but could at least for iClone if it supported Vulcan or DX12 -simultaneous multi GPUs. The other downside is the learning of another program which also seems like it will eventually replace iClone - Reallusion gives away a lot of their power directing people to other programs, especially dropping support for something another program provides. iC8 maybe could have been what Omniverse is now with an update to Iray (iray 2.0) and the above culling support, Vulkan and scatter tools which I think is already available as an open python plugin in the store. 
 
There are fees/subscriptions using Omniverse but is specific for team collaboration - hope things change but it's still awesome for what is provided.

Iclone proyects rendered in Omniverse look great.
I bought iRay, but switched to Omniverse as soon as I read that iRay won't be getting new updates

Cheers
PD. Just waiting for RL to implement a tighter integration with Omniverse

Thanks Animagic and Peter. I've been "heads down" on my current project and not able to devote any significant cycles to understanding this. In a day or so I'll take a breath and look into this in more detail :)
