A semi-fake equalizer made in UE4 based on Spider-Man Into the Spider-Verse shader with the kirby dots, half-toning, crosshatch shading. It uses a UV distortion which is then used Audio Visualiser plugin to make it react to music. Although its fake and not accurate because of the UV Distortion, it doesn't need to be linked with audio visualisation plugin. The parameters can be linked to a character's movement for stealth systems instead.
