I’ve been working on some graphics in Inkscape.
I know that Synfig is not supposed to open Inkscape .svg files but even with simple shapes the imported result is most time unusable.
To work around this problem I have tried to convert Shapes and Contours to paths, but still I’m encountering many difficulties.
Here is an example file (saved as Plain SVG):
If there are some small errors for example on tangent angles that is a bearable error, but if the position is completely wrong it becomes practically impossible to use.
I can provide many examples if that helps to fix those issues.
