The Cutout Tool is good to have, but I would like to make a perfect circle as a hole through a rectangle, as if I was using a telescope looking at something far away. Anyone out there who knows?
Hi and welcome here
You can find tutorials about this in the Wiki (about masking)
Don’t forget the main concepts in Synfig are Groups, hierarchy of layers and Blend modes
I get it now. Both methods. thank you very much!
