i have a problem. at first, i was able to 'ink' it in one piece, so my character got a black line around him, but now if i try to ink it, it sees everything individual (arms, body, legs).
How do i get it back to one piece??

:confused::confused::confused:

This means you started to use pencil or line

Break apart the lines by doing this

then try again

It's also possible that you turned on object drawing if you're using a brush. Check that.

Thank you both, i fixed it :D
