I'm currently making use of the comic border frames feature on clip studio. I've finished making the line art portion of my illustrations and I'm in the process of coloring them. However, when I use the fill tool, it colors a good portion of the illustration when my intention was to only fill a small amount of it. Trying to figure out the issue, I noticed that the panel border or frame is it's own layer and my illustration is on another layer without the borders. My question is how do make the fill tool register the panel borders so that I can fill in the colors more accurately? How do I merge the borders with the illustration so that I can use the fill tool? Any advice would be helpful.
