Hmm, this is really weird. Even after disconnecting this vertex, region one was still acting as though its tangents are linked, ignoring split tangents setting. Only “disconnecting” one of the tangents (and then converting it back to “composite”) helped. Might be some kind of bug.
If your lineart consists of many outlines, you won’t be able to auto-convert them into one region (unless you don’t mind editing .sif in text editor - it should be pretty easy there). Manually linking should work though (as long as you pay attention to drawing order).
Yeah, that’s the main downside. Though as long as you place width points exactly on top of outline vertices, it shouldn’t move anywhere (make sure “homogeneous” parameter is disabled). There is in fact a hacky way to ensure exactness: open width point in parameters dock, set its “upper bound” to amount of vertices in outline and set “position” to number of vertex it should be on top of (numeration starts from 0).
