Is there a way to put a texture over another texture in a material?

I just want to put one texture on top of another, respecting the alpha of the top texture. No adding or blending (beyond what is implied by the alpha of the top texture).

For example, given the two textures here, I want to end up with the third texture. Note that I put some extra transparency on the windows just to illustrate my point.

Linear interpolate node

How, though? Lerping between the two textures will blend them, not just overlay one on the other. It also wouldn’t include the alpha channel.

Not sure what you mean? Just plug the texture alpha into the Linear Interpolate alpha, it will “blend” exactly like you have illustrated above

Ah, there we go. That’s so obvious. Been a long day. Thanks.
