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.
