Hello There, I have recently installed the newest release for Max 2023, Im using a lamp group with a light and everything works ok but its not turning off, I can change color, intensity, use color map on the original group, but the On/Off Switch doesn't work, is this normal behaivior?

Thanks for reporting, I can reproduce this issue here. I'll pass it on to our development team.
Cheers,
Paul

Hopely I could get access to that fix, my maintenance plan will expire soon :-[

In further testing we've discovered the same issue is present in V-Ray instancer which means it's a V-Ray issue rather than specific to Forest Pack. We can't do a lot in these cases, it's something that Chaos will need to fix.
Cheers,
Paul

:o Ufff, well I can relax a little knowing that there are a couple of things that Chaos has to fix with this VrayInstancer, the Cryptomatte_Material in hidden objects and this.
Thanks Paul!!!

No worries. I've emailed Chaos to let them know.

Hi,
Further to our discussion, Chaos has got back to me. It turns out the behaviour is deliberate because internally in V-Ray, a disabled (turned off) light = hidden/non-renderable light. But most of the time you want the source object to be hidden when instancing, so they kept the logic from the case with hidden geometry.
As a workaround, it's suggested to tweak the intensity multiplier of the light instead.
Hope that helps to clarify things

Hi Paul, thanks for the quick reply, I have tested this issue with different versions and here are my ressults:
-Vray 5.2.3 + ForestPack 7.4.1
Doesnt Work
-Vray 5.2.2 + ForestPack 7.4.1
Perfection!!!
-Vray 5.2.3 + ForestPack 7.3.1
Doesnt Work
-Vray 5.2.2 + ForestPack 7.3.1
Perfection!!!
So.... as Chaos said if this is deliberate, it only ocurrs in the latest build :'( it didnt happen before :-\. Hope this issue with Vrayinstancer could be solved
