Playing around with Krita, I have found 2 options which I can't figure out how they work.
I would like to know the difference between with or without the following:

- 'Column Preference' checkbox on the Clones Array dialog
- 'Two' option of the Dyna brush

The dynamic tool simulates a sort of gravity/velocity effect:

Mass in this case affects the velocity, because higher-mass=stronger momentum. This results in a stronger effect.

Drag makes the effect more subtle by letting the brush follow the cursor more closely.

Column I don't know, I'll bug dmitry.

Thank you TheraHedwig, but sorry, I mean a checkbox labelled 'Two' in the Brush Settings panel. ('Dyna' -> 'Brush size' -> 'Shape' tab)

I am looking at the code with the "two" option with the dynamic brush. I still don't understand what this is doing - or why it would be needed. It looks like if you have the circle selected for the brush type, this logic happens

Code: Select all

 
drawCircle(painter, prev.x(), prev.y() , m_properties->diameter * 0.5 + speed, m_properties->diameter + speed);

if (m_properties->useTwoCircles) {
     drawCircle(painter, now.x(), now.y() , m_properties->diameter * 0.5 + speed, m_properties->diameter + speed);
}

It always draws with one circle, but when if you have the "two" option checked, it takes a more recent point and draws it again! I played with a bunch of different settings, but nothing seems to affect the appearance. Does anyone else know what the origin of this is? I might flag this for removal.
