3D Gaussian Splatting

[n.merazzi]

Hey TomG,

Glad to see you here.

My idea is to use Gaussian as an environment for animations and stills. If we could use (not sure if possible) the geometry + textures from 3DGP, that would be great. So, basically, all we need is to take videos on overcast days (not hard in London) and then use them as our environment. This way, we will have the real world inside our software as the background and can add our project in the middle of it. Of course, all 3DGP elements need to receive Corona sun + sky light, and even simple Corona lights, receive and cast shadows, etc. Essentially, replace the context of the project.

I would be more than happy to help.

Hi everyone!

Apparently things are moving ahead with Vray, it's a very important subject, because this capture technology is incredible, Meta has just made some great announcements, Varjo too, and even if it will never replace traditional polygonal techniques, it's fantastic for environment management for example! Today, we're obliged to integrate it into After Effect, with its 3D mode, but with Corona's 2D flat rendering .. and lot of animated masks, whereas it would be much simpler just to put it into Corona! We might as well be mixing 3Ds, rather than using 2Ds in the middle! Here's an example of a simplified drone scan for web display, and an example of an integrated model with Corona rendering. I hope this will be compatible with Corona soon, we can already do it with Blender, Houdini, UE5, Unity, .. and soon Vray!!!!

I already made a post in [Max] Feature Requests, but I can't answer it.

Already BRAVO for your work on Corona,
Thank you & nice continuation!

Best regards.

With the work completed on integrated it into V-Ray, we will be considering this for next year in Corona, as in theory all the hard lessons have been learned by the V-Ray team ;) Naturally not possible to do it this year, as our release this year has been mapped out for some time.

Wow, this is VERY good news, Tom! Speaking of what's been mapped out, the trello board is a bit empty, and I've been wondering if it's a sign of people being too busy working on stuff, or that there's nothing planned?


Nice examples of your work SA3D46. And thanks for sharing that video, it slipped by me.

[TomG]

Trello just got updated on Friday, with the things we have some level of confidence in for the next release :) Others to be added if we hit a level of confidence in them being ready. The update is purely on the next release, longer term plans are not updated (and won't be until after the 12 Update 1 release in November, as that is when we'll have a clearer picture for next year).

This is fantastic!!! Great to be able to integrate this into our workflows, game changer for capturing environments!
Lots of new advances every day, here are some useful links for those who want to discover a little more about this new approach!

Hi!

Any news on the integration of Splats in Corona?
That would be really handy! Today we have to transform the Corona renderings into Splats, mix it with the drone's Splats, and do the render / animation in After Effect! Not so easy!

Here are some examples optimized for the web,

Thanks a lot!

No news yet as the planning is yet to take place, as several of us were on quite long holiday season time off (e.g. me, as I hadn't taken much time off during the year so caught up at the year end!). We'll update Trello once we have some plans (though as always that reminder - development being what it is, Trello is a plan and not a promise, once we do get around to updating it :) ).

Just spotted this yesterday:

Wow! 
Impressive result! would you mind explaining your workflow?

Hi!

I hope it's still on the roadmap? It would be great for drone environments! Today we have to digitize 3D in splat, for integration.
After that, it's still interesting for digitizing Corona projects, as it's like a bake of geometry, material & lighting. It's always fun to walk through a Corona rendering, even in VR!

Off topic, but since we're talking about RT, Corona & Datasmith compatibility really isn't that great! Materials, triplanar, and especially scatters don't really work.
ForestPack only? Really a shame for doing UE5 projects! Disappointing from Chaos & Epic ..

Thanks & nice continuation!

Generating splats from a 3D scene was never on the road map really; the one thing that was being considered was the ability to render a Gaussian in Corona (ie incorporate it into your 3D scene). The second one is still up for consideration but not sure when, whether that might be 14 or perhaps 15 instead (as we also want to check into new innovations that don't happen anywhere, vs. "Aha V-Ray has this we should add it too"). We (Chaos) have other thoughts on the concept of walking through a Chaos scene, so we'll see what comes of that :)

As for UE, well it's a game engine, and it's approach and UI and needs are not at all geared up toward the archviz folks. This is where Vantage comes in (and Project Arena when it comes to movies and the like), where everything is much more integrated and designed for specific (non-gaming) purposes. Epic did have a phase some 5 years ago where they seemed to want to take over in archviz (and I'd phrase it that way rather than that they "cared" about archviz), but that ended 3 or 4 years ago when they shifted their focus back onto their core business of making an engine for making games.

[Stéphane Agullo]

Yes!

That's what I meant, being able to import splats into Corona would be really practical for environments. Drone scanning is very simple, the quality is perfect, and the rendering is much better than with photogrammetry or Google Earth. And once the environment is in the scene, there's no need for tracking or post-production. It's a real game changer! For generation, it's another story, today we have automated the workflow from Corona, it's a really particular approach, but it's interesting, but it's the best way to mix with drone scanning.

Otherwise, it's a shame for UE5, because it remains a very good real-time 3D engine, and in my opinion, Vantage is more of a rendering engine. Doesn't it offer the creation of a real-time 3D experience? Corona conversion is still possible, but not very user-friendly. Curious to know if other solutions are in the pipeline!

Thanks!

Title: Why Corona Needs Gaussian Splat Support — Now

As someone who works daily in architectural visualization, I was excited to see Octane 2026.1 Alpha introducing native Gaussian Splat support. With just a 15-second iPhone video, you can create rich, light-reactive spatial data — and use it directly in your scenes.

Meanwhile, Corona Render — which prides itself on photorealism and lighting precision — still has zero implementation or roadmap communication regarding radiance fields or Gaussian splats.

This is not just a missing feature anymore. It's a strategic blind spot.

With tools like Luma AI, Polycam, and Gaussian Splatting libraries becoming mainstream, artists now expect to combine capture-based workflows with physically accurate rendering.

Corona’s lack of support here creates a growing gap for visual artists who want to move fast, iterate interactively, and integrate real-world detail into their work.

Dear Chaos team, if Corona wants to remain relevant in the future of rendering, neural data like Gaussian Splats shouldn't be ignored.

The tech is there. The use case is clear. What are we waiting for?
