News / Chaos Corona 13 now available for 3ds Max and Cinema 4D

« on: Yesterday at 11:25:36 »

Chaos Corona 13 released for both 3ds Max & Cinema 4D
With Corona 13 we are pleased to be back to focusing on features! Below is a quick run through of the major features in this release.

Download: my.chaos.com/download/build?product=Corona


What's new in Corona 13:

• Toon and Outline materials. A much-requested pair of features, which are useful early in a project to avoid being locked into specific materials, or even as an artistic final render.
• Animations via Live Link to Vantage. Take advantage of GPU rendering speed for animations built in 3ds Max or Cinema 4D.
• AI Image Enhancer. Improve the look of people and vegetation in your scenes.
• Clusters in Chaos Scatter. Using noise, a color map, or layer painting, group up the objects in your Scatters (layer painting only in 3ds Max for now, Cinema 4D to follow).
• Firefly Removal. Reduce or get rid of those pesky fireflies, e.g often seen on chrome and glass on cars, or on grass, especially in animations.
• Thin Film layer. Add thin film effects in the Corona Physical Material, to give you soap bubbles, oily water, and more.
• Import .vrscene files saved out from Enscape. Save your scene from Enscape, and then get the benefits of rendering it in Corona. (requires V-Ray to be installed, even if just a trial).
• Initial support for Cosmos Variations.At download, choose which season of a tree, or which clothing variations a person is wearing.
• And much more!

Blog with full list of the smaller changes and the bug fixes will follow early next week!

[Max] Bug Reporting / Re: Corona 12 crashes all previous Coronas

« on: Yesterday at 02:53:07 »

As mentioned earlier in this thread, this is the kind of compatibility that can never happen - we'd have to go and rewrite the earlier version of Corona to handle the new parameters and data structures of the new Corona, which would mean development time spent on rewriting old code, and that is not a wise investment of development time (plus where do we stop... we add 13's functions into 12 Update 2, and Update 1 as well, what about just 12, and what about 11, and what about.....) So there is nothing for the Corona team to "improve" here, it's the nature of software when it adds new features :) The only way to avoid this is to have a time machine, so that now we finished Corona 13 we can go back in time and code the same things into Corona 12 Update 2, Update 1, and so on ;)

It can be taken as read for any release of Corona that if you save a scene from Corona version X, it will no longer be loadable / renderable in Corona version X-1 (of course you can get into fine details, and say it will be loadable / renderable so long as it did not use any of the new features or anything where a parameter has changed, but it's just safest to assume it will not load or render).

Of course what we DO take care about and can do something about is making sure something created in Corona version X-1 will load and render identically in Corona X.

[Max] Daily Builds / Re: Corona 13 RC1 Vantage

You can't export the vrscene with an animated object (the file would basically have to store the whole scene for every frame, and thus be rather huge). However, that's not the way to render animations through Vantage anyway - it's to use the Live Link, which then sends each frame over, changes only, as Vantage renders each frame. This is what is in Corona 13, so try it for yourself in the Release Candidates :) The button still calls it "exporting" the animation to Vantage, but that's not in the sense of saving a .vrscene file with the animations in it.

PS this should work with any sort of animation in the DCC - keyframed motion, light changes, material changes, particle systems, skeletal deformations, imported alembic animated objects, animation by deformers, etc. etc. :)

First thought is try Corona 13 and the new Remove Fireflies tool :) Cars with their chrome and glass reflecting the small spot of the sun is one of the prime reasons for the existence of the new feature.

Any precision date about this or time of the year? since im a teacher, the question is whether or not will introduce stable diffusion or wait a bit to fully stay in corona.

Thanks

A precision date for what aspect? For the next round of improvements to AI (no new controls, just behind the scenes changes that make it work better) - any time from tomorrow to July 10th, but nothing more precise than that. For the extended controls, no date at all other than "probably in Q3, and if not then probably Q4" (a lot of work has been done on it, and it is a high priority, so those are fairly reliable "probablies" :) ). If neither of  that answers your question, let me know!

I can confirm that is how it is today, and that there are no immediate plans for this to change (so, you won't find as soon as 13 is out and not just the RC, suddenly it costs money/credits; or that within a month, it costs money/credits). I can confirm it's been there for Enscape users for a long time and has not cost money / credits. Longer term, things are always open for change (after all, running servers costs money, so it may depend on how heavily the feature gets used, or how the cost of running the servers changes, or any number of factors both inside and outside our control here at Chaos).

No planned option for local AI Enhancing (I am guessing that is the postprocessing you are referring to). At the moment though, it doesn't cost any credits, tokens or money to use it on the Cloud :)

EDIT and I'll add that it hasn't cost any credits, tokens etc. for Enscape users for the last 6 or 8 months since it has been available there.

[Max] Bug Reporting / Re: Bloom & Glare are not in alpha...

« on: 2025-06-09, 22:05:41 »

You don't mention which version of Corona you are using. This only became supported in Corona 12 Update 2, see https://www.chaos.com/blog/corona-12-update-2 "Added the possibility to apply Bloom&Glare on the alpha render element. This is enabled by default in new scenes, but kept disabled in old scenes."

Also it means if you intend using B&G and alpha, you should use the specific Alpha render element (not the default alpha from rendering with no render elements).

The Enhancer will see some improvements either just before or not long after the release of Corona 13, which should help in things like the second case. Then later in the year the AI Enhancer team will be adding additional controls which will let you select objects in the scene to determine whether they get enhanced or not so you can further fine tune things if any objects remain problematic, and then beyond that there will be ongoing improvements to it over time as well of course :)

« on: 2025-06-09, 14:51:27 »

You could also use geometry with CoronaLight Material applied - there's no performance hit there except in the case of spheres. This would let you animated the changing rectangle with all the usual C4D controls for a geometric object.

General CG Discussion / Re: 3D Gaussian Splatting

« on: 2025-06-03, 15:27:22 »

Being able to capture the surroundings, in 3D, with just a regular phone or drone, and have it process quickly to give a relatively light and easy to work with model, is pretty astounding really. No more reliance of specialist tech, or on software that produces billions of polys and takes hours to do so, or just relying on flat 2D imagery of a surrounding area - all that kind of thing is the bread and butter of many 3D projects :)

Keep up the enthusiasm and passion!

I personally agree about the rendering of Gaussian Splats, and see it as useful regardless of whether V-Ray has recently done it or not. But we do get that criticism leveled at us, which makes it tricky, how will users interpret it - as a fantastically useful new feature and who cares if someone else did it first it's about time Corona had it regardless, or as another err... reason? to just complain that we don't innovate any more.

It is still high in the user votes, I do think it is incredibly useful for archviz, so it is very high in the running either way :) I do encourage folks to vote over the next week or two, as it won't be long before we sit down and decide what is happening next, and we'll be pulling up those votes during that process. So if you want Gaussian Splats, go vote! Or indeed vote for whatever other features you'd like to see given priority. Influence what 14 will be :)

It's 5th on the list so far, if you remove clusters and toon shading which are due in 13:

Umm, it's not ignored - we've mentioned repeatedly it is going to come to Corona, and that the decision is whether that's 14 later this year, or 15, depending on what we map out once we sit down after the release of 13. All that is said in this very thread, in fact! So it is right there at the top of the chain of things we are considering :)

Do use the AHA portal to vote, of course. In particular there is a bit of a contradictory message - "Stop just adding what V-Ray just added, and innovate!" vs "V-Ray just added Gaussian Splat rendering, add it!". So the voting on the portal will sort out which of those takes real priority for the users :)
