Chaos scatter problem (video question)

Video

the version I use is 2.7.0 the problem is in the video​
Vray 6.2.1

reverted to vantage 2.6.2 and the same problem persists there

I am not able to reproduce this (tried V-Ray 6.2 and 7.0).
You can try uninstalling both Chaos Scatter and V-Ray 6.2 and then installing V-Ray 6.2 again.
I know there was an issue if you installed Corona after V-Ray 6.2 or something similar.

If you still have the issue after that, please send us the scene.

Is this the only change that breaks the scatter update in Vantage ?
Moving the viewport icon doesn’t affect the result, so you don’t really need to move it.

The issue occurred whenever I changed any parameter. I just remembered that similar problems happened after installing Corona later. I installed V-Ray 7, mainly because the “Edit Instance” feature also works with Vantage. For now, there’s no problem. Maybe reinstalling V-Ray 6 could have fixed it as well.
Thank you so much
