  1. Luminosity based selection! New term learned! That really helps a lot I will try to fiddle with the Spare Channel tomorrow! Cheers!
  2. Hey John, It's also for Mac. It's a bit hidden. Go to download and underneath the big Windows installer button you can find the link "All Download Versions". If you click that one, you can also choose Mac OSX. I spend the whole day in Affinity working with the RGBA channels. I was able to work with the RGB channels. Not as smooth as in PS but I got some decent results. The main problem in Affinity is that it treats the channels like a coder does. So we artists need to use the eraser tool in order to "paint" black in the channels. Painting directly into the channels is very easy in Affinity. But let's assume you want to bring a b/w perlin noise or voronoi texture into one of the channels. You cannot just copy the map. You have to separate the white pixels from the black pixels. I can do this very easily in Clip Studio, but I haven't figured out a way to do this in Affinity. The PS method is so powerful, because you can just copy and then paste the b/w image into the channel. It's one single step. In Affinity or any other program you need to create an inverted selection of the stuff you want to bring into the channel and then erase in the channel by pressing backspace. Which sounds easy in first place, but you will spend some time figuring out how to set up the selection. Is there a fast selection method in Affinity where a white pixel is treated as fully opaque and a black pixel as fully transparent?
  3. Exactly the reason, why I posted. My story started with leaf textures for palm trees and ugly edges around the leaf. I use Clip Studio for most of my work and wanted to use Affinity for that. In the end I needed Krita to get the job done. In Krita just follow those steps: Create the circle. Create a second layer below the circle and fill it with the color of your choice. Duplicate the circle layer. Merge the original circle down to the color layer. Create a selection of the circle layer and invert the selection. Select the merged layer with the background color. Right click and chose Split Alpha and then Alpha into mask. This creates a mask. Select the the mask and hit backspace to remove the background. Then right click the mask and choose Split Alpha again and then Write as Alpha. Good news: Your color information are now stored! You can even save as png. Bad news: Your Background is transparent now and you cannot see or change the color easily 😜 In general: Krita seems to have some focus on game development e.g. it's easy to create tileable textures or store color information in the alpha channel. Downside: You probably have to reasign every single hot key to get an environment you can work with. And: "Working" with the "alpha channel" is also weird in Krita. I only had to create some shrubs and leaves, so using Krita was ok. But if my main job was to create vegetation on a daily basis... well... we all know the answer😉
  4. I am art director and bought Affinity products because it can handle all the print stuff we need to do in the games biz. Like the OP I had hope to also fiddle with the Alpha and RGB channel like in PS. As of January 2020 this is still not possible. Affinity Photo is marketed as Photoshop alternative. It would be great if Serif could hold up to this. But with statements like those two above, I have little hope Serif will achieve this. It's also sad to read that Serif seems to aim for semi-professionals. Whatever a "semi-professional" might be....
