#lineart layer

[drawnsnake]

Low-effort tutorial on how to save lineart that was done in the sketch layer

Go to Level Controls (usually Ctrl+L in an art program)

Move the contrast slider until the sketch is white: You may have to move it all the way, click ‘OK’ and repeat a couple of times

Go to ‘Edit’ in CSP, ‘Layer’ in SAI/SAI 2

Select ‘Convert luminance to opacity’ (wording may vary depending on the program)

Done.

Also:

After making this, I found out that Medibang has its own way of doing this called ‘Extracting Lineart’. It can be found in the Filter menu.

I recommend using a copy of the original layer in order to not lose the rest of the sketch.

This may not work if the sketch is a darker/bolder color or blended with the lineart.
