Sun and Sky with Chaos Corona for Cinema 4D

[@bobbarth6936]

Very clear, and right to the point. Now that's what I call a good tutorial!

[@ChaosCorona]

Glad you found it useful, and thank you for the feedback!

[@infojaviernova]

Thank you for this video, Corona is the best and more easy to use. With a few steps, the renders see amazing. Thank again a grettings from Spain :)

[@ChaosCorona]

Thank you for the kind words, we really appreciate it and we hope you've learned something new watching this tutorial :) Nejc

Please do a tutorial for New curvature map material effect in C4d. tnx

Dully noted, thank you for the feedback! Nejc

What were your post settings for that first scene? Because whenever I add sun and sky in my scene is totally blown out and have to put sun and sky to 0.1.

[@SeanPHafer-bn8gv]

I have the same problem. Any help would be appreciated!

[@ChaosCorona]

The post settings used were really straightforward for this one - Just some Highlight Compression (around ~3.5) and a Kim Amland's Photographic 02 LUT sitting on top of it all. The exposure was adjusted to about -3 but that obviously depends on the time of day and how bright you want things to be. Adjusting your post settings for the sun and the sky tends to be a creative ordeal and it all depends on the look you want to go for as long as you're exposure is in somewhat of a realistic range. Personally, I would recommend playing with the Filmic operators as well because controlling those highlights (really bright areas) is key when you've got a visible sun. With v8 you can also try enabling the ACES OT operator. With it you'll get a really nice and somewhat standardized filmic look happening without having to mess with anything. With it you just need to fine tune the exposure and you should be getting a really pleasing, film like looking image. And as always, if the sun's direct sunlight is just too strong for your taste it is perfectly fine to lower the intensity of the sun. In real life sun doesn't always have the same intensity - if there's a cloud in front of it the scattering will cause the direct sun light to be less intense. Hope that helps! Nejc

@@ChaosCorona Thanks for the explanation - I have/had the same problem as John Higgins. It seems like a very important detail that is not mentioned in the video. :) Love the new series - thanks for making these!

[@shynnsup8383]

I know most of these scenes have assets that can't be shared, but I was wondering that with the inclusion of Chaos Cosmos it would be nice if you guys just used those assets and were able to share these scenes with us! Great work as always.

[@ChaosCorona]

As it happens we still couldn't share the scenes, as they would contain the assets, and the assets can't be redistributed (as then people without Cosmos would be getting Cosmos assets if they didn't own Corona or V-Ray and downloaded the scene), but you would be able to download the same assets for yourself to follow along. We did that already with the two new Getting Started videos for example, so we provide the empty room, and then you can grab the same assets from Cosmos as we used if you want to have an identical scene to work with. We may use that approach again with some other tutorials :) Thanks! Tom

Nice tutorial but what was the Tone Mapping setting...? Sky and Sun adding and scene is ready... not washed out...?

[@ChaosCorona]

For an exterior, just lower the Simple Exposure (which by default is set for interiors), somewhere between -2 and -4 is usually what is required. Thanks! Tom

[@brunobordini7696]

NICE!

[@kobbygraphics8975]

I really love Corona but how can I install for my R25?

[@ChaosCorona]

The installation should work for everything from R17 to 2024, as listed on the download page at corona-renderer.com/download - if you are having trouble installing, please raise a ticket at support.chaos.com/hc/en-us/requests/new so that it reaches the support team, and they will be able to help. Thanks! Tom

If I just add a sky like that it's usually very very bright. Everything is white. Can you do a tutorial on proper exposure?

[@ChaosCorona]

Hi! Corona's exposure is set for interiors by default, so if you add a sky in an exterior scene it will be very bright - simply reduce the Simple Exposure value in those situations, that's all it takes :) Or change the aperture, shutter speed, if using physical exposure parameters. Hope this helps!

[@ilikeitwhatisit]

@@ChaosCorona Thanks, that helps. I wanted to know what the best practice is between reducing sun and sky intensity or reducing exposure in the camera.

[@ChaosCorona]

@@ilikeitwhatisit Usually best to reduce the exposure! Glad it helped!

[@gsmall7961]

so good

[@kaanguelten]

Nejc, if you read this: Thank you! :)

[@ChaosCorona]

I am sure he will read this - I will go and let him know this is here just to be sure :) Thanks! Tom

[@ChaosCorona]

Tom is a man of his word, he immediately let me know :) Thank you so much for the kind words, we are all super stoked to hear these videos are helpful to you all. Thank you a ton for your support! Nejc
