Can I use L.I.E. or Decal to project hole in a shader?

I have a dress, and am using a keyhole shape to create a cutout in the dress as an opacity map. However, when i apply a shader (as opposed to a texture map) to the dress, i lose the cutout (opacity changes to cutout opactity). I use the same map, but i cannot figure out how to make the shape line up in the correct place. How would YOU solve this problem?

You'll probably have to make your own opacity map. Open the regular texture in Photoshop or Gimp then create a texture on top of it that will be the opacity map. The white part of the map will be visible, the black will be invisible, and shades of gray will be partially visible. Then you can export that new map and use it for opacity. That's what I'd do.

Yeah I have that, but the mapping no longer is in the correct place when i add a shader. But i look at the tiling information for the map when i load it into the cutout opacity node, and make sure it matches what it was when it was in the opacity node...they don't match. im scratching my head for sure.

If you put the same map in the cutout opacity channel, check to make sure whether the tiling is set to one or whether the shader preset you applied changed one or both of the tiling values.
