Mask will not work

[spanarl]

I have been trying to paint on a mask layer added to a curve adjustment layer but the paint brush tool has no effect; it only works on the background layer. The screenshot shows the layout. I have been following a tutorial so I don't know what the problem could be. Any guidance would be appreciated.

Welcome to the Serif Affinity forums.

You're using a Blend Mode of Overlay (see Context Toolbar). Try Normal, instead.

Thank you Walt, Problem solved and much appreciated for such a quick response

I think it’s worth pointing out that Adjustment Layers automatically have their own built-in mask.

When you have the Adjustment layer selected you can paint on it to mask out whatever parts of the adjustment you don’t want – like you would by using a mask layer but without the extra mask layer.

See attached video for a quick (and crudely done) demonstration of two ways to use it.

Note: The same thing goes for Live Filters too.
