Chaos Corona for Cinema 4D > [C4D] I need help!

sky background

(1/2) > >>

Hi coronauts,

what is the right way to set the background, eg sky background?

If I create a C4D sky object and apply material- in the diffuse HDRI map slot from hdrihaven (standard or light without emit light), the sky is faded, hardly visible.

If I apply the same material in render sett./ scene environment overrides, the sky looks beautiful. The problem is that it causes white dots that only disappear with denoising amount 1!

Is it a bug, or am I doing things wrong?

please for quick help

thanks

Hi there,

It sounds like you may be doing things incorrectly. All you should need is the Corona sky object, from the "type" dropdown choose "Shader/HDRI" and then load your HDRI there. Never load an HDRI via the diffuse channel.

Hi, this is strange, I just tried it and have the same result with (left) Corona Light material in environment override and (right) HDRI bitmap placed into the Shader/HDRI slot in the Corona Sky. See the attached picture.

What HDRI are you using? Maybe the issues are related to that specific file (especially the fireflies).

Otherwise, both options - env. override and Corona Sky - should be equivalent.

koubankeo:
Thank you for the quick reply.

beanzvision: this is the case for HDRI lighting.
I want to use the corona sky + sun and put only the sky in the background.

here is a comparison

houska:
If you use sky + Corona Sky, they will be added together. That's why the first picture is so bright. So maybe to fix that, you should use Corona compositing tag with everything except "seen by GI" and "cast shadows" disabled?

 I don't wee any issues otherwise.
