Excluding objects from sky lighting?

[TeoRossi93]

Hello guys,

is there any way to exclude or include any object from a sky that is lighting the scene? Like in corona lights or light material?

[TeoRossi93]

Apparently there's no way to do this at the moment, pretty sad honestly because is useful to lit an object both with a natural hdr and a studio hdr while the whole scene is just lit with a natural hdri.

I tried with skies and light materials assigned to them, huge geometry spheres and materials assigned to them... But nothing of these stuff works...

I hope that the team will consider to add this feature in the future.

Hi there, may I ask exactly what you are trying to do?

Can't share the exact file because I have an NDA on the project right now. I will share a reference image that is pretty similar to the thing I'm working on.
Basically I have a watch in a natural environment, so the watch is lit by a natural hdri. At the same time I want the watch to be lit by a studio hdri aswell, to get nice reflections and stuff.
But this studio hdri must be visibile only on the watch reflections, not on the other stuff.
I know I can composite this by doing 2 different renders, but this project is a 45 seconds animation so it would be stupid to render 90 seconds of stuff.
I know aswell I can use some panels with light textures, but using a studio hdri is faster

And this can't be controlled via visibility options or compositing tags?

I don't understand how to make it work...

Here in this simple scene I have 2 skies ("Studio" and "Sky").
I want "Studio" and "Sky" to be both visible in the chrome sphere. I want only "Sky" to be visible on green spheres.
How can I setup the scene to do so?

Ok, here is a workaround that should do as you want. Finger's crossed ;)
1. Sky and studio is visible in the metallic sphere & the background (noted in green & orange)
2. If you don't want the studio/sky visible in the background you can uncheck it - (noted in red)
3. Sky is only visible in the green sphere's. Use the ''override'' option in the material and put a sky shader in there - (noted in blue)

I'm attaching my test scene without the HDRI map, that can be replaced with yours. I hope this helps! :)

Hi Bengamin, this is actually working pretty good but I guess the "override" option in the material is available only from Corona 10.
Since I need to render my project using Rebus Farm I think I will not be able to use version 10...
Is there any way to make this work in Corona 9?

Hi, Rebus will only use officially releases (not daily builds) and as we have recently released V10, there shouldn't be an issue for you both to use it ;) I hope this helps.
