Just curious, but has there been any behavioral changes to the smudge plugin? I went back to update a project I used it on and I can not replicate the work I had done with it before.
More specifically, when taking a stroke across an area where no color is present, I used to be able to smudge the absense of the color across a colored area. This produced a really nice smoke-like effect when used with the right colors. I've included a sample of the problem I'm having here. The top portion is the desired effect on text, the lower portion shows the "T" smudged with the new plugin. I have tried different starting positions for each stroke, further from and closer to the areas with color with no avail. Just scratching my head now.

Any suggestions are greatly appreciated.
