How to display decal on transparent material?

Hi,

I’ve got a problem of displaying a decal on transparen material/shader.

As can be seen on the image, I’ve put two decals, one directly on glass (transparent) material, second on plane (opaque). Decal directly on glass is not visible.

Is there a way to display decal on transparent material without using the opaque material in front of it?

Or is there a way to make the opaque material invisible, so the decal displayed on it won’t have any background?

Here is the shader graph of the glass (transparent) material

If you are using URP’s decal renderer, that’s just one of the documented limitations. Decals don’t work on transparent surfaces.
