Script and burn tool

range

    Values: 'burnInS' | 'burnInM' | 'burnInH'

    Get by script: True

    Set by script: False

exposure (or 'opacity' in this burn tool)

    Values: 1% - 100%

    Get by script: True

    Set by script: False

size

    Values: 1% - 1000%

    Get by script: True

    Set by script: True

Also all this ones can be get and set by script:

Diameter [1-500], Hardness%, Angle [-180/180], Roundness%, Spacing [0-1000], Flipy Boolean, Flipx Boolean

The problem is exposure

My suggestion would be to do this workarround:

For each tool, create a group of presets like this:

'burnInS010', 'burnInS020', 'burnInS030', 'burnInS040', 'burnInS050', 'burnInS060', 'burnInS070', 'burnInS080', 'burnInS090','burnInS100'

where 'burnInS010' means Burn Shadows opacity 10%, etc (you could have more accuracy with more opacity values, of course)

Then do the same for the other Ranges using

'burnInM010', 'burnInM020',...

'burnInH010', 'burnInH020',...

'dodgeS010', 'dodgeS020',...

'dodgeM010', 'dodgeM020',...

'dodgeH010', 'dodgeH020',...

Then by script you could pre-select the preset you want and put the other preferences by code.

After you have ALL the presets created you can use this code:

// Select BurnTool with all parameters
// collected from several sources and compiled
// If the preset doesn't exist, it gives a warning, telling how to create a new specific preset so the error doesn't comes again

app.currentTool = "burnInTool";

var Range = 'S';  // 'S' shadows | 'M' midtones | 'H' highlights
var Exposure = 30;  // 10, 20, 30, 40, 50, 60, 70, 80, 90, 100
selectPresetBurnDodge(Range, Exposure);

setBrushFeatures_Burn(150, 80, undefined, undefined, undefined, undefined, undefined);
