You directly connected color to the surface shader.. this works.. somekind of.. but you properly want to use the Principled Shader and use it’s Alpha input or some shader mix with Diffuse and Transparent… (i have properly mixed them up wrongly this quick :sweat_smile: )

@sbrady, please post them as images so we don’t have to switch back and forth to another tab while trying to help you. :laughing:

Regarding the question, if you want to connect alpha to the colors of the Color Ramp node, that’s unfortunately not possible, since you cannot really connect colors in the first place. It’s possible to reconstruct the Color Ramp node with other nodes though. I mean it is, it must be… :laughing: I wonder how though… :laughing: That’s if you want to connect alpha to the Color Ramp node. If you just want to use the alpha from it, then Okidoki answered that. Which is it?

Yeah, there seems to be a solution for that on Blender Stack Exchange already. So you could as well replicate the effect Color Ramp produces but with textures or colors with alpha if you wanted as well.
