Sometimes while using motion path, flipping is hard to avoid, here is one solution :
- motion path your main object to the path "path1" blue curve
- duplicate "path1, rename it to "path2", offset it, delete history and edit it to shows the direction pink curve
- create a locator "loc1" and motion path it to the path "path2"
- connect the Uvalue of "path1" to "path2" so they have the same speed
- in the motionpath1 attribute, set follow, object up and in the world up object field enter "loc1"
EDIT : Actually the best method is by far to use a curve on surface as motion path and choose the normal type. To create a curve on surface, first create a surface, then make it live and create a curve on it.

MAYA / SOuP _ Bmesh to create trees
Apply Bmesh SOuP's node on joint hierarchy to create a base mesh quickly, then adjust the size (not the scale) of each joint to change the width of the BMesh. Can change the position of the joint further, useful for tree/branches.

NUKE _ mosaic / pixellate node
Blocky - mosaic effect in nuke
If someone needed a mosaic filter in nuke, no need to turn to 3rd party plugins, or doing resizes, it's right there. Just have to load it, because it's hidden by default. It's called blocky. You can load it in your custom menu.py, by adding these lines, for example:
