Want your project in a realistic setting without having to model the environment?

Do you want to give the appearance of fully furnished rooms behind the window without having to model them in 3D?

To stop the background image being adjusted by tone mapping without using that fiddly tone map control?

Well then, Corona 16 has good news for you.

Let's begin with Gaussian Splats.

These a very popular technology chaos was at uh

so graph this year and uh autodesk university where a lot of the presenters

and attendees were talking about gaussian splats it's a new technology it's ai is not the only thing that's new

and progressing fast

and people are very excited about it current 15 already introduced the ability to render gaussian splats and also to bounce

Use global illumination of them onto the 3D objects in your scene, helping things blend together much better.

But Corona 16 goes further.

Now scene lighting can illuminate the Gaussian splat.

This also includes the option for self shadowing.

The end result is that your Gaussian splat

and your 3D objects all look like part of the same world and they all blend together beautifully.

For that final little touch, you can always do a quick pass through Verus,

and then you can end up with a wonderful image of your 3D objects placed in a Gaussian splat environment, or indeed, the other way around,

your Gaussian splat object placed in a 3D environment.

Of course, with the addition of Max having its own Gaussian splats, Corona 16 can also render those, no problem.

You'll also find that Corona 16 can now load SPZ format, which is a particularly highly compressed form of Gaussian splats it's a format

that makes them smaller than ever a repeated request from you

all was to make the sky volume effect better occasionally the

old effect would have color banding strange colors in it

that were unwanted and we fixed that for corona 16 a small thing

but one you've been asking for displacement looks fantastic

but it can be very memory hungry when you're actually displacing geometry

so another request that we've had from you all is to use Pavellax displacement.

This doesn't move any geometry and it saves a remarkable amount of memory.

In this example, it saved about 20 % of the memory compared to geometric displacement.

If you're building a street view or a city view,

you don't want the windows of your buildings to look like they lead into a blank empty space.

This is not the back rooms you're trying to render here.

Instead, you want it to look like those actual rooms behind there.

Thing is, you don't want to spend time 3d modeling the interiors lighting them etc well

there's a solution for you now with parallax interiors

you simply add a flat plane use one of the parallax interiors from cosmos

and it looks like your room has a full 3d scene

in it including parallax effects as the viewer moves from left to right

when you're using a background image quite often you do not want it to be affected by the vfb

or the CIE tone mapping.

This was possible using the tone map control.

It was a bit fiddly to use and it couldn't undo all the tone mapping changes, things like ASUS OT,

and it also meant you had to do IR restarts

if you did adjust the tone mapping to bring the background back to its unedited state.

This problem's a thing of the past now because both the VFP

and the CIE have a new background option

that lets you place a background image into them

and it remains completely untouched by any tone mapping and you don't need to restart anything ever.

This lets you use the tone mapping to match the look of your background image,

editing the lighting and appearance of the 3D parts of the scene so that they blend well with your background.

Or indeed, you can use it more creatively.

We're continuing our quest to bring you a better connection between Corona and Vantage with many improvements to the Live Link.

They'll scroll past on the screen here.

I'm looking to read them all, and you can find them all in the changelog.

You don't need to try and read them as they zip by.

We've heard your concerns with the very large file sizes of CXR files.

So first of all, in Corona for Cinema 4D and coming to Corona for Max later, we are offering the option to save to 16 -bit,

which greatly reduces the CXR file size.

The clever part is anything that needs to be 32 -bit, such as a cryptomat or an object ID, remains 32 -bit.

And anything that can be reduced to 16 -bit without impacting the output is reduced to 16 -bit.

This can result in up to 45 % file savings in some examples, possibly more, possibly less depending on just how much

you've packed into your cxr continuing with c4d we've improved the viewport preview of materials probably the biggest is

that glass and similar are now actually transparent in the viewport we've also made it

so that the front back map shows in the viewport and

that mapped glossiness shows in the viewport and also

that triplanar works properly in the viewport

and some other things too again full list in the change log over in cosmos

you can now generate 3d assets using ai

if you give it an example image like this one here it will go ahead

and create the 3d objects based on

that image you just need a single image and then you can bring

that into your scene and render corona 16 also introduces the ai assistant it has a set of skills

First, we'll have a look at the sky match.

Start IR so that the AI assistant can see your render, give it a reference image,

and it will update the HDRI to give you a matching result.

Plus, it will add a look to do some color grading for you.

And then the assistant can help you create scatters.

For example, here's a nice empty scene, and I asked it for rocks and plants that you would find in a Utah desert.

I have no idea what rocks and plants you'd find in the utah desert

but it goes and uses cosmos semantic search to find suitable plants based on your description

and then creates scatters for you bringing those plants into the scene

you can then manually adjust those to get just the result you want

and then of course the most basic function the help function

you can ask it a question um about say how to use the corona ao map

and it will give you an answer

but most importantly for me it will give you all the references

that point to tutorials documentation help desk documents and similar

so you can go and read up on it for yourself

if you're new to 3d

or just starting out with corona we have the render critique in the assistant

this will give you a guide on what the ai thinks to your image it'll give it some scores

and it will give you some helpful advice on how you could improve the scene

and this can be anything from camera angles to adjustments to the render settings

now as i say this is a training tool we don't expect anyone who's intermediate

or experienced to be making use of this

because it'll just be telling you things you already know

but for those of you starting out it should be a good way to get some guides

and advice on what to do next to bring your renders

100

to the next level over in veras the new node editor has been introduced

101

this lets you create a series of nodes in order to

102

carry out your ai tasks rather than just have to do a single prompt

103

and to make that easier to get to we've added links to veras

104

and the ai enhancer and upscaler into the corona image editor

105

and then a small thing we've added the chaos notification center

106

this is something you entirely control the only thing you can't turn off is critical advisories

107

and these are things that you really want to be notified about

108

if there's going to be some sort of planned license outage hasn't happened

109

but it can happen and that's something you definitely need to know

110

so it doesn't interrupt your work everything else is up to you it's optional

111

you can turn it on you can turn it off now you never need to miss a corona update again

112

Again, if you choose to leave notification about updates enabled, but again, we've left the control to you.

113

And with that, there is actually one notification to give you just now, which is, that's the end of this video.

114

I'd like to thank you for watching, enjoy Karina 16, and hey, we'll see you next time.

シャドーイングとは？英語上達に効果的な理由

シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
