How to create distance haze

[3dkobi]

Hi guys,
I'm doing an animation of a ship in the ocean and I need to produce some kind of haze in the distance so the sky and the ocean will almost merge. I'm pretty new to corona and never did such a thing. How should I approach this ?
Any help is much appreciated....
Peace,
Kobi

On Vray I got good results using a large "donut" shape filled with fog near the horizon. You also need to take care of the attenuation on the waves far away from the camera, that will help a lot to get a nice blend with the sky.

Thanks sirio - I'll try your idea...

I'm interested to this topic. Teorically you should use a corona volume to simulate fog or the haze you want.

Yes, but I don't want the fog to interact with the scene - just need it in the horizon

It depends how accurate you need it to be - a simple option would be put your scene inside a cylinder (with no top or bottom) and map a gradient into the onto the Opacity so it fades up into the sky.

If you wanted it to be more accurate you could do the donut/ring with Corona Fog material assigned, or in the Global Volume (https://help.c4d.corona-renderer.com/support/solutions/articles/12000035577-how-to-use-volumetrics-) - and then play with the various options in there.

Cheers, I'll try that

i would second that. fog is universal in your scene if you want fog you need to put it everywhere. you need to adjust the volume material to get the desired look i guess. if you need fog in the distance only, maybe try faking it in post? render out IDs to isolate the ship, bakc and foreground.

Yep, I already see I can't get good results in the render so I'll do it in post
