I’m interested in seeing what i can do with the paint tool in Blender, this should be fun. =)
Whoops, just found out what falloff does, next image won’t be so blurry or small.
you can use brushes, too! have you seen http://mediawiki.blender.org/index.php/Manual/Texture_Paint ?
You know when I looked at that I thought that could be used as graffiti on a wall.
The tool looks like it’ll make great stencils, dirt maps, and graffiti.
I think Blender’s current paint tools constitute a fairly competent paint application. The only thing I’m missing are multiple layers with blend modes. Since multi-layer exr files are supported now, I guess it is only a matter of time before they get a ui in the uv/image painter 
Kitsu: I know, it’s awesome, and
CD: You know, that’s totally what I was thinking. I’m working on a set called the Room of Tears, it’s an alley-way, and the walls are covered with graffiti. If I use a brick texture on 1 UV map to tile across the walls, I can use another,wall-sized UV map for the graffiti and texture blending and stuff.
Is there a way to -
- import a .abr file (or gimp brush file) into Blender?
Maybe Blender should have it’s own brush file system (or borrow gimp’s since they’re both open source?) I’ve got masses of brushes, bringing them in one at a time will suck.
- paint in the 3D window instead of the uv editor window?
Put these two things together (layers would be nice too, but I can live without them for now) and my UV problems will be history.
Yup, you can paint in the 3d window. Go into the 3d window and set it to ‘texture paint mode’ 
HOLY CRAP!!
Baby, where have you been all my life? 
O.K., I can see I’m going to become one of the chief proponents of this.
Here’s my next question - only one level of undo?
We need brush outlines in the viewport too.
Where do I go to help develop this (not a programmer, I mean artistic input)?
Found a few more problems -
2056 textures aren’t big enough (can’t display more in viewport).
Pressure sensitivity doesn’t resize image-based texture brushes.
Pressure sensitivity doesn’t control opacity well on image-based texture brushes either, but “airbrush” is a decent workaround.
I’ve got most of it figured out now. I don’t know where my earlier problems with texture brushes and size and opacity sensitivity came from. They work fine.
