I think that Artrage is just simply the closest thing to real time painting that I have found. Thank you to the art rage team!
One thing though, I notice in working with two layers where the top layer is a soft light blend layer. I can merge the two layers succesfully mantaining the soft light effect. Repeating the process for another portion of the canvas, I notice that I can achieve the soft light blend again a second time, but the first soft light blend on the bottom merged layer is lost, the color reverts back to an unwanted color scheme..
Any thoughts on this would be appreciated.
