Thank you for the reply eishiya. I’m using version 1.2.25-x64. I’m a complete beginner with pixel art and Aseprite, so I didn’t even realize that I can adjust the settings for the blur tool. Now that I found the settings, I managed to get the blur tool working the way I wanted. The problem was that I had all the dynamics settings deselected. When I enabled the gradient setting under mouse velocity, I got the tool to work like expected. Thank you for the help and for your time.
