It pains me to give anything related to AI props, but I asked chatGPT to write me actions to control post processing for Unity 6 and it actually gave me usable results.

I just want to write here, maybe it helps, I had this problem for years since I m using Playmaker.
I also wrote here in a different post, I also couldn't use Ecosystem because of that null error, I couldn't even download the ecosystem package from the website, everything was happening on a specific computer. For example using my phone, I could download the ecosystem package, but on the main computer I couldn't, it was showing an error page.

I finally managed to fix that null error. It s a problem with the computer, it's blocking github. Go to C:\Windows\System32\drivers\etc, open hosts file, search for github, delete that line, save it, restart the computer
That fixed for me.

As the title says.... I´ve tried dropping the post effects profile itself into playmaker and got a grey out "post effect actions" function.

Because now it´s basically standard to plug in effects into the stack, how can I access the variables ? For example I need to set the fog color of the "Better Fog" plugin.
Is there a way without exposing those variables ?
