The color is a vector parameter and the zero is a constant so right click and search for them and assign them to the relevant outputs and don’t forget to change blend mode under materials in the details panel to translucent to enable the opacity property.

Hey guys, i think it will be more optimal to use Masked blend mode, not Translucent. And connect Zero to Opacity mask, not to Opacity.
