A friend of mine brought up an interesting point about paper grain. It would be nice to have a button in the paper settings that would reinterpret the strokes applied to a layer based on a new papergrain setting. I have actually wished for this kind of functionality myself. Say, as an example, I have painted an image for a client and used a grain that looks like paper. Upon review the client indicates a preference for a canvas grain. It would be of great value to be able to make that switch happen.
I know not what I ask.
