"Warning: Post Process Materials - the native property is not tagged as BlueprintReadWrite, the "

I’m using the Make PostProcessSettings node and have toggled Rendering Features > Post Process Materials.

When I compile I get the following: Warning Post Process Materials - the native property is not tagged as BlueprintReadWrite, the pin will be removed in a future release.

Is there another way to set post process materials via blueprint?

I’m interested in this as well
it says the pin will be removed in a future release, but IIRC this message has been there for a long time. Also I didn’t find any other way to do it
