Adaptive-Blended TAA, a tiny magic for your sharp and responsive scenes

Just decided that i too will make a post to show you a tiny little trick with the shader code of TAA, that can make it look sharp and responsive, without the obvious artifacts of trembling, noisy pixels and wandering jaggies.

I ended up reducing the blend factor to 0.5f, as it seems to reduce jitter on very noise stuff. Temporal AA sharpening - Rendering - Epic Developer Community Forums
There might be some stuff that is more visible by reducing this, but in my scene it looks rather nice.

BlendFinal = clamp( BlendFinal + sqrt(sqrt(distance(BackN.xy, UV.xy))) * 0.5f , BlendFinal , 1.0f );
