How can i use the undo brush non destructively ? Is it somehow possible with masks? What i want is a layer/masklayer i can blend in and out only with the changes of the undo brush.
Hi! I’m enjoying Affinity Photo, but have a question about the undo brush (or history brush not sure the official name). When I use it on a pixel layer it appears to work fine at first. But then if I hide the underlying layers (or look at the resulting thumbnail image in the layers panel), it becomes clear that the undo brush has, while performing the undo function, also cloned everything it’s touched from the underlying layers. So areas that were originally clear in the layer on which I was using the brush are now filled in with colors from below, creating a problem for further editing of the image. Could someone please let me know, is there any way to set the undo brush to leave clear areas on a layer clear, and not fill them in with content from the underlying layers? Thanks in advance!
OK. I'm flummoxed. Figuring out the Undo Brush, I've understood everything, except how to use the Blend checkbox. All I want is a simple example that shows it working. I've spent ages trying various history panel and snapshot fiddles and I'm darned if I can see anything different happening. Help!
Masks are a huge part of my image editing workflows. One of the only things still keeping me partially tethered to Photoshop is how that program manages masks with other tools --- particularly its brush blending modes, color picker, and history brush. Brush Blending modes and Masks -- Blending modes like Lighten and Darken are invaluable when doing meticulous mask editing, or when painting with a mask. Lighten would allow you to paint in slightly less opaque portions of the mask without altering already existing opaque portions, while the Darken blending mode would provide the opposite functionality. The Color Picker and Masks -- When you have a mask selected, the color picker could choose a gray/black/white directly from the mask for you to paint/fill/etc with, which makes intuitive sense and is extremely useful for being precise with edits, even with a gradient of grays in the mask. The Undo Brush and Masks -- Another great way to increase the options for editing Masks would be to allow the Undo Brush to work with them. Currently (as of Beta 1.7) nothing happens when you attempt to use the Undo brush on a mask.
