Hi Jaira, I’m sorry you are having this trouble. It certainly sounds like your “lasso limit” has been reached long time ago. Having 47 frames with several layers should not be a problem at all. The problem comes when the data of one frame is growing too large because of extreme lasso use 😉 Also that data can be copied and multiplied to many other frames with the lasso, spreading that large lump of data around. This makes the system very slow (when lassoing again, not while playing or drawing) and the file size enormous.
Best way to stay out of this problem is to not use the lasso too much. If you need to copy a drawing, drag down a clone and then make it original using shortcut o. Or use copy/paste in the X-sheet.
I know this is also about how we are used to work – and like to work. Some people use the lassoing method a lot. Sketching/drawing the next frame instead of building it out of lassoed pieces is a better way of doing it for many reasons. At least that is how many animators like to do it. But I think Animation Paper aught to cater to both types of animators of course. So we will find a solution eventually to this.
For now, to get your file up and running again, I recommend copying your problem-file, and then go methodically through it to find out first which layer(s) has the problem. Delete them one by one and save for each time. If after deleting a certain layer it suddenly has a huge drop i filesize, you found your problem layer. Depending on how many frames it consist of you could redraw the drawing one by one. You often do this anyway as you do your cleanup or inking. Redraw (trace) on to a new layer and get rid of the old messed up layer. Then save again and you should have a clean file taking up next to no space and being super fast to work with.
I hope this will help you.
I just want to say, that this lasso problem is my responsibility to find a solution to. It should not be up to the user to have to change behaviour. I know, how it works right now becomes a problem for some users – luckily most people use it as I thought it would be used, so they are not affected. 🙂 And even though I know you and others are suffering because of my design, I hope to make it good again as I figure out a way to fix it.
Best,
Niels
