Changing material colours with Sound visualizer ?

Hi folks,

I’ve just started using the UE4 Sound visualizer and while can get my models scaling in time to the music, I’d like to change the colour of the material depending on the volume, and use that colour information to drive a lerp so that I can use it to make interesting effects in the material editor.

Any help would be gratefully received.

Many thanks,


Yeah you just have to clamp in range both values. In one hand the Sound Output and in the other hand (for example) the HUE Value of your material color.
