So you want the brushes to smear more than blur? ASP is really good at this.

With the smudge tool selected in the toolbar pick a smudge brush (or even the pigment brushes are good for this) and toggle Pattern, Aux Stamp, Jitter, and Dynamics off.

In the wetness section, set Blend transparency to 'Full', turn off blend radius (to disabled)
set Mix Rate to around 15
Set wetness to at least 50% or more
Turn on 1px spacing smudge
Turn off dynamics, and make sure flow is 100% since these can really affect everything else.

Make ake sure your brush stamp is a simple shape to start.  There are other settings that affect blur/blend but start there.

Test that out on some flat color swatches (no space between them) to see what it's like. it should just pull color away from the swatches without blending them (but will blend with the transparency). Then incrementally turn blend radius up to a value you like -> he larger the radius, the more color averaging/blur will occur.

let me know how that works.

open the menu (three bar icon in upper left) click Artstudio > Preferences > Interface > left hand mode. It is the first option in the second section.

I recently started using a Bluetooth keyboard when drawing/painting. Its great! However, In the manual there is a section of keyboard shortcuts called 'additional shortcuts' where brush size and other parameters can be set with 'held' key combos such as ctrl+option, but that section isn't in ArtStudioPro editor.

Since it is now in gestures section rather than the shortcut editor, I guess its not possible to customize it, but it would be great if that were an option. I'd like to have single key for changing the size as its much easier than having to holding down two.

  Just saw that the two previous topics are in preferences already.

Under Tools: 'Show cursor at the last stroke location when resizing' & 'Show brush preview always in the corner'.

I may have derailed this thread by fumbling about the preferences and tools... but the brush switch preview thing is still interesting, to me anyway (first post). I don't have an iPad with hover, but it would probably be nice to get a quick preview when switching tools/brushes, even with that feature. Anyone else think it would be useful (or not)?

Try these brushes:
Mixers > Full Mixer
Mixers > Full DYnamic Mixer

Thanks!

I found that too - it has to do with 'auto clean brush' being turned off. Turn it back on and the color picker goes back to normal.

Switching brush tools:
Similar to how the layers flash to indicate which layer is active, quickly displaying the selected brush stamp on screen when switching tools (and therefore size) will be useful. This will show the user if brush needs to be resized or not without having to make a stroke and possible undo if it's not the right size. The amount of time the stamp will be displayed would be adjustable like other settings such as eye dropper long press delay.

Resizing brush tools:
I don't find the brush display (dark square) all that useful and prefer the cursor to be near my fingers when resizing like the elastify tool (when cursor outline is on). This way brush size can be gauged over a specific area. Currently the brush stamp stays at the last stylus position.

Art studio pro has options for showing cursor/brush style given various conditions, but if you don't like the cursor visible when applying paint and set it to none, you lose the ability to see the outline near your fingers when resizing the brush or elastify tool. An option for showing the brush cursor when resizing (and hovering if available) but not when painting would be great.
