Thanks for the tips!
I spend an entire day just figuring out a viable way to get those parameters in a post process material working.
It seems everyone has difficulty working with parameters in post process materials.
Even seen posts from 2014, and it didnt get much easier today.
I only got it to work by making a new “Dynamic Material Instance” and overriding what is in the “Post Process Volume”.
However trying to access the editor assigned “Post Process Material” in a “Post Process Volume” is a lost cause.
I just could not get it to work.
The option with the “MakeFloat4” node worked for me. I can now push random colours to my Post Processing Material.
I also explored the option with the “Material Parameter Collection”. This also works.
The tip about the masks to convert float4 to float3 was also nice.
