spsorrel Posted February 21, 2020 Posted February 21, 2020 Hello: I have just noticed that when I try to hide part of an object or painting, Affinity Designer has different results depending on using Eraser or a black brush: As you can see, both are masks. Using brush tool selecting a 100% black, it doesn´t paint 100% and part of the rectangle is still visible. Eraser paint 100% black and hide successfully the part painted in the mask. I think this shouldn´t work like this, right? Thank you very much. Quote

spsorrel Posted February 22, 2020 Author Posted February 22, 2020 Hello Michail: By steps: 1. I draw the rectangle. 2. I change to pixel persona. 3. I take a basic brush: 4. I grab the brush tool. 5. I change colour to 100% black: 6. I keep opacity and flow at 100% and I do not protect alpha: 7. I create a mask keeping 100% opacity. 8. I paint and the result is: I dont know why you get the part of the square completely hiden, but I cannot get that unless I use eraser tool... Thank you very much. Quote
walt.farrell Posted February 22, 2020 Posted February 22, 2020 You're using a Hardness value of 0 for your brush, which gives a soft (sort of feathered) edge, as you can see at the right-hand edge of the blue part of your rectangle. It also would give you a smaller apparent brush size (narrower brush). Possibly with that hardness setting you need to go over the areas you're erasing again, to make sure you've really painted black over everything?

spsorrel Posted February 22, 2020 Author Posted February 22, 2020 Hello walt.farrel: That´s not the problem, I have passed the brush many times and the rectangle remains visible at its righ part. Thank you. Quote

But did you try bumping the hardness to 100 to see if that resolves it?

Thanks for the detailed documentation. When I look at the result, I can only think of two possibilities: The brush color is not really black. It looks more like a 90 percent black. Check it again. Draw a line and then double-click on the corresponding color field of the color selector. You may have set an accumulation of less than 100%. Check this by clicking on the "More" ("Más") button at the top of the context bar. Do you work with a mouse or with a pressure-sensitive pen? Can you possibly attach the file? Quote

It shouldn´t make any different, but I have just tried and it gives the same result. 9 hours ago, Michail said: Thanks for the detailed documentation.

Staff Sean P Posted March 26, 2020 Staff Posted March 26, 2020 Hi spsorrel, Sorry for the delayed response. Is your document using CMYK? There is a known issue that 100%K doesn't fully remove masks when using CMYK. Quote
spsorrel Posted March 27, 2020 Author Posted March 27, 2020 Hello Sean P: Thanks for the answer. Yes, I think it was in CMYK. I don´t really remember it, but I used to use the preset of A4 (ready for printing), and it is configured in CMYK. I have tried in RGB and it works as expected: 100% black brush erase 100% the shape. Thank you. Quote
spsorrel Posted March 1, 2021 Author Posted March 1, 2021 Hello Sean P: Revising some questions asked time ago, I have been awared that this issue is not solved in the last updates, only for remember it to you. Thanks. Sean P 1 Quote
