YOUTUBE | BLUEPRINT USED

The effect that I wanted to give this environment, an oil painting look, required a post process effect that wouldn't just effect the player camera/viewport but the world and materials of objects as a whole.  The post processes on marketplace weren't really looking like what I wanted so to do this, I used a tutorial to make this effect adjustable and customizable while understanding how it works. The blueprint required to make this effect work is to use a normal map as a world aligned texture that will be linked to a scene texture post process input. Then creating parameters for the material instance created from the post process material to be able to slide the variables like the effects intensity, scale, and saturation. This effect places a normal map across the world like a layer, so anything within the post processing volume will be within the tiling range of this normal map. So when intensity and or scale are adjusted, it changes the world align on the world's UV and distorts it. This gives the world, not just the viewport of the player, a "painted" look.
