when i open a blender 4.4 2d animation file in 4.5 and try to draw on a existing frame , it just removes the other drawings on that frame why?
it is not an issue with additive framing , coz I’m trying to draw on an existing keyframe , and this issue does not occur when I try to animate in a brand new project that is build from 4.5 version. When try to erase in that frame , erasing works with no issue , but trying to use the brush get rid of any existing brush strokes
If you share the file I can take a look and let you know; as a quick fix you can try, open a new 2D animation file, and go to the top bar file->append, navigate to the old file and select the grease pencil object(s) you made in the old file. It will import it in the new scene and it should work.
