How to paint selection area (a.k.a. quick mask mode)

[Y.H.Lai]

How could I paint a selection area in Krita? In Photoshop it’s called Quick Mask. I’m pretty sure there is a similar feature in Krita, but I forgot how to activate it. And the Krita document site is down now so I can’t search for it.

I think it has something to do with “Global selection mask”, but Global selection mask doesn’t show up until I have selected some region. I’d like it to switch to a mode, similar to PS’ Quick Mask, where I can just paint selection with whatever brush I’m currently using. Is it possible?

I belive this plugin is what you are looking for:

Paint selection (test)

[demo2] Posted a request for this a few days ago, and then realised that, it’s not a good idea to modify selection mask. I make this plugin to use a paint layer for selection. It works (though not perfectly). I still want krita implement this as a default tool. Caution This plugin run slowly and would crash krita when paint with big canvas(like 4000x4000 at 300ppi). Don’t press too quickly with big canvas. Usage Default shortcut is ‘A’. Press shortcut, a temporary layer is added, do norm…

Maybe I’m wrong, but hope that not.

If there is no Global Selection and you enable the Show Global Selection Mask option then a black Global Selection Mask is created.
If Show Global Selection is already enabled and there is no selection, you can toggle the Show Global Selection Mask option to create a black Global Selection Mask.

I usually do like this:

1. Create a selection on the canvas with any selection tool;
2. Press the “Q” key on the keyboard: whatever is out of the selection will be red;
3. Take a brush. By painting with white, you add to the selection; painting with black you subtract;
4. When finished, press the Q key again.

It seems to be the answer. After assigning a shortcut to “Show Global Selection Mask”, it works pretty much the same as in PS.
