Limit Atmosphere to One Light?

[Anonymous]

I have a scene with a spot light and atmosphere behind some trees. I also have a quad light used as a fill to give more definition to the main object in the scene. However, the atmosphere volume is also emanating from the quad light, which I do not want. Is there a way to limit the atmosphere volume to one selected light only?

Thanks.

What about setting the Volume contribution to 0 on the Main tab of the quad light?

Thanks! That was so obvious, I can't believe I didn't think of it.

Hi Peter, it may seem stupid or obvious but I cant find the Volume Contribution option in the main tab! Would you be kind enough to give me directions?

It is in the Attribute editor of every light, under the Arnold section, open the visibility tab. It is the 5th parameter.

when i put 0 to volume attribute , area light is not emitting any light . what to do now ?

Volume samples: 0 will disable the light. You need to reduce the 'volume'  contribution slider to 0 underneath it in the UI screenshot above.

You won't be able to 'see' the light but you will be able to see the objects it lights (if your exposure is high enough).
