Where to place Opacity map of decal?

[travis.designer.vn (Travis Nguyen)]

Hi

I download this decal on Megascan website. There are Albedo and Opacity Map. I’m intent to place this decal on a wall, It mean need wall material and decal.

I select object then select Decal tab, I only can place Albedo map, where could I put Opacity map?
Or other method to create Decal in Rhino 7?

Combine them in your favourite image editor and save out as PNG with alpha channel.

For instance with GIMP:

Addendum for a bit more control over the texture if the decal is the only texture you’re going to have:

Emboss a signature on glass

If you look to do this just for rendering, I’ve just uploaded a video of how you could do this: [Texture mapping logo on bottle - Rhino 7]
