Hi all! Fairly new to chief architect and needed some help with the screen capture material. As you can see, the outlines are squared, so I was wondering if anyone has some advice or recommendations on how to help minimize it? Or even blend it out, so it flows all together. At first, I thought it was because I didn't crop it correctly, but as I zoomed in, it showed that the line connected, right? I also tried to find a way to make the pattern myself and paint it white afterward, but I couldn't figure it out. Any suggestions/advice would be appreciated. Thanks so much.
