I am almost there...the raft floats along the river path, but once it makes the first turn, it is floating sideways to the river. I need the raft to turn to facedown river at each turn.
I tried orient to path, but that flipped the raft upside down!
I don't think orienting to the raft sideways will be possible with the one image. I think you'll need several frames of the raft as it turns sideways, then a graphic of the raft as it looks going downriver from a different angle. Else, it's going to look very odd as you try to shift the perspective to make it look right.
Aaah, I see what you mean. That concept had escaped me.
