I am new to Synfig and I was having no problems until I grouped my Spline with my other layers. Now when I make a new shape it doesn’t appear (the outline does when I select that layer) and when I imported an image it was inside my spline. Anyone know if i clicked some setting by mistake?
Completely uninstalled, opened my project and the problem was fixed.
Maybe you changed the blend method on the toolbox, this could cause the behavior you were experiencing.
