i have this pixelation post-processing effect for my retro game. I applied it to the level using post-processing volume and have the pixelization amount set as a parameter, so that the player can adjust the amount to their liking.
The issue I’m having: How do I bring-up the material instance in the blueprint editor to change the value? I’ve searched and “set scalar parameter value” seems to be the thing, but I cannot find how to actually create a reference for my material.
Anybody knows how can I set the parameter value from a variable? (In this case, the slider value)
