![]() ![]() I doubt a single video is going to do justice to the integration of alpha in layers. Why are you fixating on the alpha channel of Photoshop? Other than the Pencil icon, there's no way to tell in AF. In Photoshop, it's obvious when you're editing the alpha channel as the color palette turns to grayscale. It just makes the corresponding alpha channel white no matter what the current foreground color is. But when I draw with the Paint Brush, for example, it draws in the RGB channels. You can see from the screen capture, I have the Composite Alpha channel editable and the others not editable (the Pencil icon). Coming from Photoshop, it seems simple and obvious. I've tried what you showed in your screen capture (see the attached image) MANY times. I don't mean to hijack this thread, but I too am confused. When I first started using AF, I didn't realize that layers had to be rasterized before you can edit them, so maybe there's some step required for alpha channels that I'm not doing. I'm not really sure, as I've not yet gotten it to work.Ĭlick to expand.I don't mean to hijack this thread, but I too am confused. You have to convert the alpha channel, then edit it, then convert it back. ![]() The Pencil icon (makes a channel editable) has no effect on the alpha channel. In PS, I can edit the alpha channel as if it were a grayscale layer, for example, paint or fill with any gray level, do effects like blur, anything I can do in any other layer. In Affinity Photo, you can fill an alpha channel from a selection or mask, but you can't actually edit it. It's just a toggle that turns on and off viewing the unfilled background of an image. In Affinity Photo, Transparent Background doesn't actually add an alpha channel. It's saved as its own channel in a TIFF file. A grayscale alpha channel determines the image's level transparency. I sometimes also need transparency in 3D textures. For example, a UI button with rounded corners, or a button with a drop shadow or glow. ![]() Click to expand.I'm using the alpha channel for transparency. ![]()
