I'm experimenting with the digital watercolor tool of painter 9 (specifically the "new simple water" brush) and I like it, but... I can't get anything to affect it after I put it on the canvas... not any blending tools or erasers or anything. http://www.zemotion.net/noah gets some really nice effects with Painter's watercolor tool, but I have no idea how he blends colors together like that using painter... I can kind of do it in photoshop, but painter is still kind of foreign to me... I'm having a hard time with it. Help?
