Rotation (Surface Align) issue

[ldotchopz]

I am trying to add feathers to a leg using tyflow but i having some issues aligning them to the surface correctly. I have done similar things in the past with no problem. My geo seems fine, i have checked their normals, i have reset their xform. but the feather always appear skewed in random directions in certain areas.

At the end of the video i show my results using Forest pack which appear correctly, but i would much rather do them in tyflow.

Am i missing something key here?

Cheers!
