Not sure if its me doing something wrong but im unable to edit a layer mask using the black and white paint brush?!

Ive created a mask and now need to amend small areas of it so was expecting to paint white and/or black on it to adjust accordingly. But all that happens is I get is the mask being erased no matter what colour I use.

 

Any one else have this issue?

There's nothing selected. If there was should it not stop me from editing anywhere outside of that selection? i.e. you wouldn't see the erasing that is happening unless im within the bounds of the selection? 

A further note even if I right click on the Layer Mask and choose 'Edit Mask' it only 'paints black'.

After a restart however it seems to work.

File attached anyway.

Yes, i deleted my question because that's not the issue. A selection would prevent any kind of painting and we are still seeing the strokes even if they act weird. Seems a pontual glitch to me. If you close the app, reopen the image again and try to paint on the mask does it work correctly?

To save time I am currently using an automated AI to reply to some posts on this forum. If any of "my" posts are wrong or appear to be total b*ll*cks they are the ones generated by the AI. If correct they were probably mine. I apologise for any mistakes made by my AI - I'm sure it will improve with time.

I vaguely recall this happening in the past if im not mistaken. I thought it was me not doing something correctly and went back to Photoshop. Its working as of right now as I say after a restart, if it happens again I will let you know.

Haha thanks for spotting that too MEB I totally thought I was going mad. Sumpin' definitely wonky it's broken again after working after a restart. All I did was change the opacity in the slider Carl pointed out and now the paint brush no matter the colour is erasing the mask again.

When you switched to white paint for the Paint Brush Tool, but continued to paint black, the Colour panel showed both white and black. Weird bug.

hmm... maybe this is why I really struggle to get my head around using colours in Affinity. Also Trying to reorder swatches causes a crash to desktop which I submitted quite a while ago. It’s still not fixed in 1.8.4. Maybe I have a very wonky installation regarding colours, swatches and panels?!

Hi Marilynn,
Are you sure it was the Opacity value that was set to 0% in your case for your foreground/background colors? The issue above is a bit hard to replicate from the information on this thread alone. Seems there was some steps taken before the video was recorded that leaved the app in a weird state. Can you give us more details about your case please? Thanks.

I have the same problem. I cannot paint on a mask with the paintbrush.

If I invert the mask (ctrl+i) I can paint in white with the color replacement tool.

As I try to show the mask as: (overlay, white/black/transparent) nothing happens.

It is a new effect I did not see before I upgraded to 1.8.5.703

I did all the standard steps like restarting the computer and reinstalling (repairing) Affinity photo.

I have had the same difficulty for a long time, I entered the forum in search of an answer. I will see if at the end of the reading I find the answer, if not I will continue investigating.

The problem still persists on Affinity Photo 1.9.3 and Big Sur 11.4 Mac OS when using an image stack with two images and a corresponding mask layer assigned to  each of them.  It does not paint white on top of black in the mask layer. The color and opacity settings seem totally fine. Restart does not help.

Welcome to the Serif Affinity forums.

If you mean an official stack (File > New Stack) then I think that masking is handled somewhat differently, with some special rules for how masking works. I don't think that would cause what you just described, but I think it might be better for you to start your own topic, and to provide screenshots showing the Layers panel, and possibly a sample .afphoto document.

This was probably my lack of knowledge problem. Did not know that setting flow to anything lower than 50% doesn't do anything to the mask layer. Fixed now.

To paint on a mask Layer the Primary and Secondary colors must be in Grayscale. 

The Default on my file was RGB.

I would like to know if this fix works for others.

Hi @MarlaAu and welcome to the forums,

When you add a Layer Mask by either clicking the Mask icon at the bottom of the Layers panel or going to Layer > New Mask Layer, the mask layer itself will appear as a greyscale Layer.

If you want to invert the layer you can use Cmd + I (Mac), Ctrl + I (Windows) or use Layer > Invert...

You can paint in any color mode on masks, no need to use greyscale.
all colored will be automatically converted when applied on a mask layer, only the lightness will be used.

Hey, I think I managed to reproduce the problem.

So far, every layer I turn Layer Effect > Outline on, the layer mask starts bugging out when I try to use white/black on it. It just acts like paint and not mask. I am on a Windows PC with the newest update.
