Glad it worked.
It's not just one solution, that I did in that attached file.
My previous solution would have worked also, only if we moved TySpline Mesher modifier bellow bends modifiers.
Any solution will work once you have stable geometry (non changing topology) with deformations.
Cheers bro.
P.S. I am still puzzled is there actually TyFlow way to have particles attached to the splines vertices.
