NvRTX Caustics: Future support for Substrate?

Gaming and Visualization Technologies Engines Unreal

Hi there,

A question: With Unreal Engine moving towards Substrate (and 5.7 having it enabled by default), are there any plans to support this also in future versions of the NvRTX Caustics branch?

Oh, and on the side: Are these questions better asked on the Discord channel or here?

Thanks :)

Good morning Nvidia,

Any input on this? It would really help us to have some information on this so we can plan our development.

Cheers,

VTY

Sorry VTY for the late response.

The NvRTX branch maintainers are sometimes active on the Forums, but I don’t think they are on Discord.

I can’t answer your question, but I will ask them to reply if possible.

Thanks!

Hi Marcus,

Thank you for your efforts.

Any input from the maintainer team would be greatly appreciated. I of course understand their time is limited, but for our side it’s quite relevant to have an idea of what to expect.

The Caustics branch is truly unparalleled and I hope it will continue to develop for years to come :)

Hope you have a great weekend.

Hi @MarkusHoHo and happy new year!

Did you manage to get any response out of the maintainers on their plans for the NvRTX Caustics branch?

Thanks for pinging again!

I got some answer, but not enough information to share yet, so still digging.

Okay thanks. Looking forward to the next update :)

Hi Marcus,

Sorry to push, but do you have any news? We’re really eager to move to UE5.7 (even without substrate, for the time being) because of stability and performance. Very much looking forward to the NvRTX 5.7 release.

Thanks for your support.

Pinged internally once again, but no further news I am afraid.

Hi Marcus,

Can I please ask you to ping the maintainers once again? It would be great to have more insight into the release planning :)/

Thanks for your support!

Hi @MarkusHoHo ,

Just a little nudge (and adding your ‘@’ to the message) in case you didn’t see my question.

Again: Also a 5.7 release without Substrate would be very helpful. We’re stuck on 5.4 since the other (5.5 and 5.6) releases have other issues that we can’t work around).

Any news on this would be greatly appreciated.

Wish you a great weekend,

VTY.

Hi VTY,

yes I saw that and I did reach out internally, but nothing new. I am sorry.

Now comes GDC and GTC, so everyone is busy.

In all likelihood there might be plans that are simply not available to be shared publicly and don’t have an ETA.

But I keep asking.

Hi @MarkusHoHo,

Thanks for your reply. It really helps me to know that there’s someone at the other end of the line ;-)

Good luck with GDC/GTC, just a few more days to go!

I’ll send another message in a month or so, to see if there are any developments.

Hi @MarkusHoHo ,

With GDC/GTC now behind us, can you maybe give the devs another push on NvRTX Caustics for 5.7?

Would be great to hear Nvidia’s direction on this.

Thanks, as always, for your support.

Hi!

As far as I could find out there is only one person currently taking care of Caustics. They are also responsible for a lot more projects beside that. Which means further development and specifically how it interacts with Substrate is on rather low priority at the moment.

In short, no new updates and no details on direction or ETAs.

I am sorry.
