I have been driving myself crazy trying to make my own frequency separation action with median blur, or even dust and scratch, instead of gassian blur. I’ve kind of given up, but I would realllly appreciate that feature!! I really hate gassian blur for frequency separation.. and also the mixer brush doesn’t work like photoshops... I have to manually click “clean brush” every time I make a stroke, so if Affinity could add “clean brush after each stroke”, that would be AMAZING!! If anyone has made their own frequency separation action, or knows how to make it with median blur, please let me know! Would be a life saver❤️
