Blend /Lerp node?

melviso

I am wondering why there isn't a blend node with alpha like in other material editors. The Lerp node doesn't allow you to multiply, add or overlay two textures with a plug for an alpha texture. If I am not mistaken Lerp uses the Normal like photoshop blend mode. Is there a way to blend using multiply, add, overlay, subtract e.t.c  two textures with a channel packed mask?

Probably because doing this with nodes is pretty straight forward. In case of adding them using an alpha, you just multiply the alpha on B before adding it to A. You could definitely make some custom material functions for this.

Overlay would be done like this:

Multiply:

Add:

Subtract would be the same as add but instead of the add node you have subtract.
