Hello, I started with the tutorial and things worked fine. However, I don’t know if I accidentally changed my settings or what, but whenever I try to draw a new circle or rectangle my old one disappears behind the grey checkered empty space. In other words, I can only have one shape visible at a time. Also, when I use the sketch tool, I cannot get rid of what I sketched. I expect there is a face palmingly simple fix. Please help.
Sounds like your default blend method is ‘straight’. Try switching it to composite.
For sketch, look at the tool options for the sketch tool (just under where it says ‘Show Sketch’) There’s options to undo last stroke or clear the entire sketch.
