I've imported my own hands, following the size requirements. However, they flip around while drawing, instead of remaining upright. Does this in the preview and with my actual art alike:
How to fix? Thanks!
You can import one or two images to make your custom hand. If you only import one hand image you can use it for moving an image in (Move-in). If you set a single image hand to 'Draw' an image (as opposed to 'Morph' or 'Move-in') it will rotate as in your GIF.
When you import two (slightly different) hand images these are used for when 'Draw' is selected on the image as opposed to 'Move-in' or 'Morph'
