Title: Sky and clouds through the window?
Post by: iacdxb on 2024-10-28, 04:30:06

Hi,

Build a scene and one window is only source light inside room with sky and sun light.
Outside is so bright clouds are not seeing... how can I see clouds through the window...?

Thanks.

An override for the environment seen through refraction, and in there place the sky through a Color Correct then Tonemap Control to disable the effects of exposure in the VFB / Camera, then you can independently adjust it's exposure with the Color Correct. Remember that you need to restart the render if you change the scene exposure, for the Tonemap Control to take effect again. Depending on scene, may also need the override in the reflection and direct visibility too.

Thanks Tom.
Sky through color correct and tonemap...? These are sharers and sky is object, where to place these shaders under sky..?
I am not using any texture or backplate for sky, just simple corona sun and sky using.
Possible to make c4d file... easy to study and understand.

Thanks.

If you turn the sky object into a shader/hdri object you can then pick plugins>corona>sky. Then you can add stuff like color correction etc to it like a normal shader.

What i like to do in similar situations is to assign rayswitch material to the window glass, add tinted glass material to its direct slot and regular glass to the rest. Then you can adjust tint strength and control exterior exposure that way.

Actually, this is brilliant!

I'm going to try this too.

For now we use two skies; one for background+reflections+refractions (less intesnity) and another for GI lighting, that way you can also configure as fits...
and also a select material for the glass  making it darker/more physical glass woth volume when making outside views and passing to thin clear glass for the interior views
