Tutorial HDRI Environment and Overrides in Corona Renderer for 3ds Max

[@wathsalamelan924]

this is what i seeking everywhere on youtube, thank u so much, well explained.

[@Electrion118]

We want more tutorials from you guys!!!

[@ChaosCorona]

For sure! You will get them :) Tom

[@georgekarapetyan3782]

Very useful, thank you Aram.

[@skeopaip7722]

Very well explained! A massive thank you!!!🤩🤗

[@LEEHOANGDESIGN]

To adjust the brightness of the HDRI background, you can typically control the exposure or brightness settings in your rendering software. For the issue of tilting when using HDRI in sphere mode, ensure the horizon of the HDRI aligns correctly with your scene. Additional adjustments might be available, depending on the software you're using. If you're experiencing differences from Chaos Vantage, check specific settings or documentation for consistency. Could you specify the software you're using for more detailed guidance?

highly useful ! thank you!

Is there any way to preserve the post-production background in Corona tone mapping? One of the things I miss in Corona is not being able to maintain the same original lighting in the background without the post-production affecting it, especially when dealing with areas where there are translucent objects. Creating masks doesn't always help.

[@ChaosCorona]

Not 100% sure what you mean - the Corona Tone Map Control is probably what you need (docs.chaos.com/display/CRMAX/Corona+Tonemap+Control+Map ), but if that doesn't answer your question, please post over on the forums at forum.corona-renderer.com/index.php?board=29.0 with more details and examples (images, scenes, screengrabs) that illustrate the problem, and the Support team will be able to see that there (as will the Corona community, who are also very helpful!). Thanks! Tom

[@GorArakelyan]

Hello, are you sure that increasing HDRI intensity is similar to increasing the exposure? I guess not. Brighter light creates hard and dark shadows, while increasing exposure you boost the overall sensitivity to light. Please let me know if I am correct.

[@ChaosCorona]

Results will be almost identical - brighter light creates hard dark shadows would be true for a single light, but with an HDRI that has a whole sky, this is not the case, as you are increasing the light that gets into those shadows as well (as there is some light coming from every direction), and we can add in the effect of light bounces too (brighter light being bounced, potentially into shadow areas). And raising exposure of course, the shadow areas similarly become brighter. This means it is safe to choose whichever approach you find easiest or that "makes most sense". If an HDRI is at a different exposure (not all are equal) you can adjust that to save tweaking your camera exposure; or if you prefer to think of it as the real world where you can't adjust the exposure of the sky, you can adjust the camera exposure. Either way differences in the look will be pretty trivial. I can't share a comparison photo here on YT, the forums allow for that kind of thing though :) forum.corona-renderer.com/ Hope this helps!

@@ChaosCorona Thank you very much!

[@ChaosCorona]

Most welcome!

[@navneetbansal2608]

Thanks a lot, Its very useful.

[@MrBastille]

why don't you use the osl environment , it has more options for hdri than the Corona bitmap?

[@ChaosCorona]

Our tutorials focus on how to use our tools (but of course people are welcome to use other tools, if they work with Corona and they prefer them :) ). Thanks! Tom

[@nekosan01]

OSLhave terrible UI and not in all 3ds max versions

[@shinajvlog]

awesome, very useful

Glad you found it helpful! Happy rendering! Tom

[@luislemperle2563]

Hi, I am currently trying to figure out what the best (and least buffering) method is to create grass and vegetation in general. In this video the grass and vegetation looks amazing! Do you have any video or post/blog about how to do that already? If not, is a tutorial on that in planing? P.S. thank you so much for trying to answer every single comment! Its really appreciated!

[@ChaosCorona]

You are welcome, we try to reply to all comments as much as possible :) You can download the scene for yourself, see the description, it's an Evermotion scene - so you can take a look at how they set it up. For learning how to create this on your own, search for the scatter tutorials here on our channel, there are several e.g. kzbin.info/www/bejne/q4m2qmuvpbWDi7M and kzbin.info/www/bejne/a6K1Y5yYgLZkY5o should be the two main ones. Hope those help! Tom

[@Eagleizer]

I'm on 3dsMAX 2020 and Corona 7. I have the Corona Lights available, but nothing in the Slate Materiel Editor as you show. What's up with that you think? (So I'm lost since Corona is not listed anywhere in the right-click menu)

[@telefonkirtys]

Have you changed your render engine to corona in render setup panel (f10)?

[@ChaosCorona]

Sorry to hear you are having an issue. First best thing is to upgrade to Corona 9, lots of new features and who knows, the installation may fix this along the way. Failing that you can always submit a ticket at support.chaos.com/requests/new and our support team can help out (they can't monitor KZbin comments). Hope this helps! Tom

[@andreravenna4435]

Would love a longer indepth vid about the new Corona Physical material.

[@ChaosCorona]

That will be coming :) Thanks! Tom

[@andreravenna4435]

@@ChaosCorona any eta on that?

@@andreravenna4435 All we can say is it is in progress and being recorded. We don't give out specific dates, because then people will get annoyed if it is earlier or later than we had anticipated :) Thanks! Tom

thanks you so much good explained....

[@deabeatovikj3845]

Thank you for this tutorial. I cannot extract the scene after I download it. Does anyone else has this problem?

[@ChaosCorona]

You are welcome about the tutorial! For the scene, probably best to contact Evermotion about any issues with it as they created the scene and whatever file format it is compressed into. Hope this helps! Tom

[@Sagar-cd7sc]

Sir please help my hdri is not showing render time

[@ChaosCorona]

Sorry to hear you are having some problems. Unfortunately, it's not possible to provide technical support via KZbin (as we'd need screenshots of scene and render set up, or need a back and forth with Q&A, none of which KZbin allows for), but we'll be able and happy to help if you open a ticket with us at support.chaos.com/requests/new - you can even send in the scene, privately direct to us, which is always a big help as we can then look directly at what is going on. Thanks! Tom

[@cleberrodrigo8720]

why don't you do more tuts for C4?

[@ChaosCorona]

We haven't done many tutorials for either version lately, just due to the focus on things like the webinar (and this one is simply an update to an old video). Rest assured we continue to balance work on tutorials for both :) Thanks! Tom

When it's coming for revit??

[@ChaosCorona]

Sorry to disappoint, but Corona is not being developed for any host application other than the two we currently support. Tom

[@nonononoura]

HOW did you open the enviroment? Im stuck there

[@ChaosCorona]

The process is shown and described at kzbin.info/www/bejne/p5DTpaiwn7GlnbM - can you say which step in that process did not work for you? Thanks! Tom

[@siphiwekheswa9785]

How do I download Corona render as a standalone without 3ds max

[@ChaosCorona]

The Standalone is in the installer for either version. Of course, it doesn't do anything unless you have a scene exported into the Corona Standalone format.... Hope that helps! Tom

[@siphiwekheswa9785]

Thanks.will it work with a core i5 11gen CPU?

[@ChaosCorona]

@@siphiwekheswa9785 Corona will work on any CPU from the last 10 years (Corona required the CPU supports the SSE4.1 instruction set); you can check specifications at corona-renderer.com/getting-started. Hope that helps! Tom

Direct Visibility doesn't work at me.

[@ChaosCorona]

Sorry to hear you are having problems - we'd need a lot more info though, and the place to share that is via ticket support.chaos.com/requests/new or via forums forum.corona-renderer.com/index.php?board=29.0. When writing there (our support team can't monitor KZbin comments) please explain more about what you mean (Direct Visibility render element? Environment Override Direct visibility? Rayswitch Direct Visibility? Most likely second one, but we'd need to be sure :) ), which version of Corona, the scene or at least screengrabs of your set up, which host software and version, and a clearer description of how it "doesn't work" (e.g. adding a different HDRI into a second Corona bitmap and using that in the Direct Visibility of the Env Override does not replace the HDRI in a first Corona Bitmap in the Max Environment slot). Thanks! Tom

[@ryekwung]

Effective！

Except that it's 1000x more complicated that what it seems

[@ChaosCorona]

Hi! Can you give some specifics on what you found complicated? That way we can consider doing follow up tutorials on those specific topics. Thanks! Tom
