Material cookies for area light leaks to other irrelevant point light volumes

[JLChnToZ]

I think this is better to explain with recordings.
I'm currently trying V3 dev version, and have setup area lights for dynamically emitting screen content, using pointLightVolume.SetCustomMaterial(material, autoUpdate) to toggle it whether update or not, but somewhat the texture leaked to other point light volumes unexpectedly. Wondering if I'm doing anything wrong or it is an unfixed bug?

It's very weird, never experienced that... Gonna investigate. Thanks for the report!

I tried to make a small fix... Maybe it solved the problem. Check the latest dev.3 release

If it didn't fix the problem, I might need to cooperate with you in discord if it's possible! Tell me and I'll DM you. Thanks!

Cool! I will get back to you when I back home to test it out.

The new version doesn't fix the issue, but I think I know something.
The world I shown above uses a bundled Filamented shader, and it does includes its own version of "LightVolumes.cginc", which is V2.
And I manually swap out that cginc to latest one, it works!
So I can confirm which don't work is when shading with compatibility mode (old version).
