How to Edit Post Process Material Parameter

[Arcade]

@SVR33;430291

Trying to do the same thing in 4.10 (creating a dynamic blendable material instance) and I get the following warning from my “Make Post Process Settings” node:
“Warning Blendables - the native property is not tagged as BlueprintReadWrite, the pin will be removed in a future release”

So, how do we change blendable parameters on the fly, then?

+1 over here. What to do without the Blendables-node?

Thanks,
