Previously, there has been a post on fixing an issue relating to Synfig; the longer you attempt to make an animation, the laggier Synfig gets. The solution to this problem, according to the post, is to set unused scenes’ “amounts” to 0. I have tried this solution, but it has little to no effect on Synfig’s speed.
So far, the only way I can reduce lag in Synfig is to do as the author of the post did; uncheck unused scenes through the “layers panel.”
This is why I’m reaching out to you, Synfig! Do ya’ll suppose you can allow for adding waypoints to represent when a layer is checked/unchecked in the “layers panel,” or just make Synfig not render objects that are invisible or not in the canvas?
