Issue using isolate light inside Light Editor

Hello Arnold devs, I'm on Maya 2019 with the latest Arnold version,

I'm currently facing some issue when switching between lights, Arnold doesn't update the renderview with the correct light isolated, even if use the "Update full scene" or toggle multiple times the isolate icon. The only workaround I found was to add in isolation the lights you don't want to affect the render and then un-isolate them to force the renderView to update.


That'll be great if you could fix that in one of our next update.

Thanks!

I tried it with a few lights and it seemed to work. Does it happen with all lights or one specifically. Tbh, there are a lot of lights in the scene. It would be ideal if you had a scene that had one or two lights that demonstrate the issue. Could you simplify it further?

I'm having issues when switching the isolate selection. I was doing the pre-lighting, and isolated every light in the scene to handle their way of lighting, so switching between lights using "Isolate light" icon inside the Light Editor and you should also encounter the same issue (hopefully).

Thanks for the scene. Could you explain the exact steps required to reproduce the issue, please?

Ok. If you are able to provide a simplified scene that reproduces the issue that would help us identify the problem.

My scene is pretty heavy, will contain more than 15 lights, I think that can affect the way Maya handle the lights.
It also contains some empty light nodes because sometimes I deleted lights but it didn't correctly updated the Light Editor view (also Right click -> delete / DEL button / Close and re-open the light editor does not get rid off these empty nodes).

But until yet I found a workaround to make isolated light(s) work, I just scroll inside the "Light Editor" and it updates the Arnold Renderview. Weird thing that a scroll event does affect the renderview this way, I can't imagine the code behind that...

I never thought to use the Arnold Light Manager, will do it and back here to say if it fixes lights issues or not, thanks!

I just tried it now and it seems to work. Is there anything special in your scene? Can you upload a reproducible scene. Does it work with the Arnold Light Manager?
