Next 2 and Next 1 render different

[18322119@qq.com]

I have an old scene which Next 2 renders much brighter than Next 1. And I tested with Vray 3.6, the result is same to Vray Next 1.

Attachment is the scene.
Run the commands to reproduce:
> YourVray4.1Path/bin/vray.exe -sceneFile=e1.vrscene -imgFile=4.1.jpg
> YourVray4.2Path/bin/vray.exe -sceneFile=e1.vrscene -imgFile=4.2.jpg

Hi，Lele,

I've read the thread.

The thead was talked between 2018-10 and 2019-05. So the thread was comparing Next/Next1 with 3.6.
Accoring to Next release time:
- Next was on 2018-9
- Next 1 was on 2018-11
- Next 2 was on 2019-6

The core problem for me is Next2 renders more brighter than Next1. Is this a known issue in Next 1?

Duh me, sorry.
Glad Peter sorted it.

Thanks for the provided files and information. This is a known issue - there is a difference in the GI between visible and invisible Mesh Lights. Our developers are already informed about the matter. As a workaround and to match the results, set the invisible value of your mesh lights to 0.

Thank you Aleksandar. The workaround works.
