im looking for answer how create animation without shapes only with pencil
Short answer: You can’t.
Longer answer: The Pencil tool was not designed to do animation, only for sketching guides and such which are not meant to be animated. This might change in the near future, since the development priority for January is “Frame-by-frame animation (bitmap)”.
You can also draw individual animation frames on a image editor program and then import the images to synfig to make the animation, but that method is a bit cumbersome.
Alternatively you can use other animation programs which allow to directly draw individual frames, like Tupi.
thank you once again
