I am using Photoshop CS5 I am trying to use a layer mask when I apply the mask the paint brush has no effect on the layer. I made sure I was using my default black and white colors and I insured the the mask was selected on the layer panel my brush flow is at 100 and still nothing happens
One other place to check, to make sure that the Layer Mask is active, is the Channels Panel.
Also, do you have any Selection in the Layer Mask, maybe one that is Hidden?
Another question: when you went to paint into the Layer Mask, did the Colors change automatically, or did you have to change them, yourself? That should be automatic, if an Alpha Channel/Mask is active.
If it IS active, and the Paint Brush is not painting IN, or OUT, then I would Reset the Brush Tool.
I'm having similar problem. Using Photoshop CS5.1 I am trying to select layer mask. I have active layer /highlighted blue/ and when I click on layer mask, white border shows around layer mask thumbnail. I select brush, check mode: normal, opacity: 100%, flow: 100%, colors set to black and white ->but instead of revealing, brush is painting on image.
When I use layer mask on photos everything works fine. Now I'm trying to use it on vector shape made in photoshop and is just not working.
What am I doing wrong?
I have already restarted Photoshop and replaced PS settings.
I have pressed "Q" to deselect quick mask. I wasn't using it - just to make sure.
What else can I do?
