History/Art History Brush Painting White, help?
Hello,
I can't find an answer to this online. I'm trying to use the Art History Brush. I've Masked a cat, and Merged the cut out cat onto a blank layer that I'd painted white. I added a new layer to paint on with the Art History Brush but it's painting white rather than cloning the image from below. Does anyone know why this is happening?

If I try to use the Art History brush before Merging down onto a white layer I get the below error message.
