Here is my example: I create a new image and open tracing paper. Using color cloning and the glitter tool, I create a glitter copy of the tracing paper. If I then try to use the palette knife to smear the glitter, some of it is wet, and some of it is not.
What affects whether glitter is still wet? Does it dry whenever you change a tool or setting, for example?
In case it is relevant, I am using the new release (2.2).
